      i think i have a solution :
      instead of squid use squid3_dev .

      in custom options :
      "
      acl venticinque random 1/4
      acl settantacinquediv2 random 0.5

      tcp_outgoing_address 192.168.4.1 venticinque

      tcp_outgoing_address 192.168.3.1  settantacinquediv2

      tcp_outgoing_address 192.168.2.1

      "

      i have three wan with different speed so i try to balance the throughput with different weigth

          first install squid3-dev  from available packages.

          ++++++in this way you can use configuration directive acl random .
          from squid doc :
          changes in 3.2 acl : random

          New type random. Pseudo-randomly match requests based on a configured probability .

          now you can do all the configuration you need for multiwan in Custom options - Custom setting of proxy server.

          in my situation ( 3 wan ) :

          "
          acl venticinque random 1/4
          acl settantacinquediv2 random 0.5

          tcp_outgoing_address 192.168.4.254 venticinque

          tcp_outgoing_address 192.168.3.254  settantacinquediv2

          tcp_outgoing_address 192.168.2.254

          "

          192.168.4.254 = ipv4 address wan 1
          192.168.3.254 = ipv4 address wan 2
          192.168.2.254 = ipv4 address wan 3

          random 1/4 = 25 % = wan1 25% of traffic
          random 0.5 = (100-25)/2 = wan2 37,5 % of traffic
          else = wan3 37,5 % of traffic

          i do this because my 3 wan are not equal.

          in case of 2 wan :

          "
          acl cinquanta random 0.5

          tcp_outgoing_address 192.168.4.254 cinquanta

          tcp_outgoing_address 192.168.2.254

          "

          you do not need extra rule on firewall ( floating rule ) .
          Also it bypass gateway groups.

              squid3 need lib update.
              check  squid 3.3.4 package for pfsense with ssl filtering

                So i understand but some ppl using wan interface for bridge mode (pppoe)  .
                what they can do bridge (pppoe) users.
                and some ppl have dynamic wan ip adresses.

                  hi, here it does not work the "acl random" always comes out with the wan1.
                  I have version 2.1 and squid pfsense 3.3.8-dev pkg 2.2.

                  here is my custom options

                  acl fifty random 0.5 (I also tried 1/2 instead of 0.5)
                  tcp_outgoing_address fifty 192.168.100.2 (no gateway ip, ip pfsense wan1)
                  tcp_outgoing_address 192.168.2.3 (not ip gateway, ip pfsense WAN2)

                  here continue to browse only the wan1 while if I disable the transparent proxy balancing works well.
                  Works to you?
                  how did you set the "outbound nat" in automatic or manual?
                  thanks
                  bye

                  –-------------------------------------------------------------------------------------
                  correction, with the "Automatic outbound NAT rule generation" everything works.

                  Thank you, Regards

                    Hi,

                    nice idea with the different tcp_outgoing addresses…
                    I found yesterday also a site which show this option (before I found this thread ^^):
                    http://linuxaria.com/pills/setup-squid-to-use-multiple-outgoing-ip-addresses

                    This thread seems the only one (with "content") who mentioned that there is a bug in pfSense 2.1 with floating rules.
                    Because of right topic I add my information here, too.

                    Since update from 2.0.1 to 2.1.0 we have in remote office also the problem that only our default WAN interface is accessible from outside... :( Here my test from yesterday night; we are using there 1st WAN with PPPoE, 2nd WAN with local modem-router.

                    Here each a test to http://ident.me :

                    Interesting part: the 1st line connects over backup WAN Interface with right IP but to wrong destination port... and every repeated initializing packet goes to right destination port but over wrong main WAN interface ?
                    
                    I was thinking about testing today if there is a difference between localhost and lan interface by accessing remote pbx but I forgot to deactivate floating rules so the employees had tested it before I had time for it ^^.
                    
                    Using normal rules works nice so it must be a floating rule bug... 
                    => Is it perhaps possible easy to fix it with a "remote github" patch ?
                    
                    First I was not sure if it's really a floating rule bug because
                    [list]
                    [li] incoming connections to firewall on slave WAN interface are unusable since update, too.
                    If you have same problems here the solution:
                    => I fixed it with NATting:[list]
                    [li]WAN1:22   => localhost:22,[/li]
                    [li]WAN1:443 => localhost:443,[/li]
                    [li]WAN2:22   => localhost:22 and[/li]
                    [li]WAN2:443 => localhost:443.[/li]
                    [/list][/li]
                    [li]DynDNS service can't be updated anymore, too...
                    But the service should be bound on 2nd WAN interface directly?[/li]
                    [/list]
                    
                    Bests[/s][/s][/s][/s][/s][/code][/s][/s][/s][/s][/s][/s]

                      mmh… addititional strange behavior... I manually run / later re-checked on webgui.
                      The registered dynamic name service is registered to use WAN2 ... but got IP from WAN1 and switched here to wrong IP

                      Perhaps better for a new thread:
                      Why is checkip.dyndns.org used for other dyndns services ?
                      Would be nice if checking service can be made selectable.

                      I knew its is / was a nice service. But since yesterday I don't think so anymore…
                      I used them for my SQuiD loadbalancing tests... and got 127.0.0.1 back :D

                      Also DynDNS won't check IPv6 addresses because they say in their supportforum it would always stay same IP.
                      Ok this should be normally the case (especially for firewalls) but it would be nice service to get them either in response for re-check settings.

                      http://ident.me offer IPv6/IPv4 address and showed me yesterday 127.0.0.1 and the right local IP address in answer page.
                      http://v4.ident.me only IPv4
                      http://v6.ident.me only IPv6

                        Hi,

                        on normal usage a very nice option ;)

                        @ruggero:

                        i think i have a solution :
                        instead of squid use squid3_dev .

                        in custom options :
                        "
                        acl venticinque random 1/4
                        acl settantacinquediv2 random 0.5

                        tcp_outgoing_address 192.168.4.1 venticinque
                        tcp_outgoing_address 192.168.3.1  settantacinquediv2
                        tcp_outgoing_address 192.168.2.1

                        I justed tested it with this additional ACL RegEx (needs perhaps some improvements) so we can let Youtube videos through the good line and block it in the not so good backup line:

                        acl_youtube urlpath_regex http://www.youtube.com/watch\?v=.*
                        acl wan2 random 1/2
                        
                        tcp_outgoing_address <wan1 ip=""> youtube
                        tcp_outgoing_address <wan2 ip=""> wan2
                        tcp_outgoing_address <wan1 ip=""></wan1></wan2></wan1>
                        

                        Pitily there is a problem if one of the lines are down… then every x request is timing out... :(

                        Is it perhaps possible to let SQuiD know by local files/checks what lines are up?

                        Not very RAM friendly would be a solution to run for each WAN interface a SQuiD instance and in front of it the main SQuiD with these SQuiDs as parents... then he can auto-select/fallback as he is allowed to ask them by rule.

                          @Reiner030:

                          acl_youtube urlpath_regex http://www.youtube.com/watch\?v=.*
                          acl wan2 random 1/2
                          
                          tcp_outgoing_address <wan1 ip=""> youtube
                          tcp_outgoing_address <wan2 ip=""> wan2
                          tcp_outgoing_address <wan1 ip=""></wan1></wan2></wan1>
                          

                          ah, squid3-dev matches irregulary in transparent mode also urlpath_regex - correct is url_regex.
                          And I added further sniffed URLs also for HTML5 blocking (perhaps too much, but better than too few ;)):

                          acl Youtube_Streams url_regex (youtube.com|youtube.be|m.ytimg.com|s.ytimg.com|s2.ytimg.com|s3.ytimg.com|googlevideo.com)/(.*\.(flv|swf)|player204|stream_204|watchtime|generate_204|videoplayback)
                          
                          tcp_outgoing_address <wan2 ip=""> Youtube_Streams</wan2>
                          

                          Actual my testing "live" pfSense goes out only on WAN1 even I set tcp_outgoing_address onto WAN2 IP ???.
                          So I can't test it correctly but I guess it can be made shorter like this with ReGex:

                          acl Youtube_Streams url_regex (youtube.com|youtube.be|m.ytimg.com|s\d*.ytimg.com|i\d*.ytimg.com|googlevideo.com)/(.*\.(flv|swf)|(player|stream_|generate_)204|watchtime|videoplayback)

                            I downloaded the lib modules for squid 3.3.8 from the following link

                            http://e-sac.siteseguro.ws/pfsense/8/amd64/All/ldd/

                            please let me know that the acl random method solve the issue? and if the one Wan goes down what will happen then?
                            it will send all the traffic to valid interface or it will still keep sending the packets to failed wan also?

                            need clarification on this.

                            Thanks

                              Its for us not an urgent task to use loadbalanced proxy and I had problems to getting SQuidGuard+SQuid3-dev both run.
                              So I downgraded to stable SQuid and we use the fibre line as normal (with youtube bound to this wan ip).
                              If the gateway failover then only non-youtube video content can be loaded.

                              I used the i386 one on an Soekris appliance http://e-sac.siteseguro.ws/pfsense/8/All/ldd/ added like here described:

                              … ah just updated.... updates fetched... I must see If I had time for testing it out next weeks when less work is to do.

                              Bests

                                Finally, after a long time trying pfSense Squid Package + Multi Wan and I have managed to find its way in a deadlock.
                                pfSense 2.1 Squid Package + Multi Wan, no longer using the Floating Rules, but using the Interface Groups.
                                Good Luck Everyone.

                                  Thanks, and congratulations!

                                  What version of squid and squidguard are you using?

                                  Please send a screenshot of your system->routing screen showing your default route.

                                    Still configure the same as pfSense 2.0.3 Squid Package Multi Wan, only changes to the Floating Rules to Interface Group.

                                      I wondering what's squid version you talking about 2.7 or 3.8 or it doesn't matter?
                                      secondly where you use interface named "internet" I saw it has no rules, will you be more detailed

                                        Under the Menu=> Interface, you can see Interface Group.

                                          Created the interface group. Squid uses the default gateway only with 2.1.

                                            • Im try for squid 2.7, you can try for squid 3.8 you can tell me later for the result.
                                            • If you expert configure for inbound/outbound for WANs under Interface Group.. Actually that use for WANs rules not for LANs rules.
