PfSense 2.1 Floating rules for Multi Wan doesn't work.

Hi,

on normal usage a very nice option ;)

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.

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.

hyrol

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

@hyrol
Thank you ..
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

SaFi

hyrol

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.

niebla

The problem is squid is using the default route and does not care about interface groups. What am I missing?

hyrol

Actually this is not Load-Balance Round Robin, this is Load-Balance Bandwith Agreggation and you can see all the WANs its working.
It is worth it from nothing.

How does Squid know to use the interface group instead of the default gateway?

hyrol

I do not know how Squid works, most importantly it works. ;)

niebla

Squid works with multi-wan on 2.0.3 by using floating rules. Users have reported that it is not working with 2.1 with multi-wan even when using floating rules.

Many users are looking for a way to use multi-wan and squid using 2.1.

When this is solved many of us who have squid and multi wan will be able to use 2.1, and be grateful to the person who provides the solution.

I have followed the same steps but all in vain,
squid still uses only default gateway :( does not work with Interface Group

still waiting to fix it…

hyrol

If you check whatmyip you can see only default WAN, but you can see all the WANs work together.

Note: This Load-Balance Bandwith Agreggation not Load-Balance Round Robin.

niebla

My tests show that squid is only using the default gateway. I understand and have the interface group. It can be used by rules but is not being used by squid, which has a large majority of our traffic.

hyrol

pfSense 2.1.1 soon be out, hoping the problem will be solved.
