      For me its hard to understand what your configuration looks like.

      Can you make a picture with paint with your switches, routers and IP-addresses / subnets

          default gateway and dns of network client is pfsense
          gw 192.168.10.10
          dns 192.168.10.10

          with this, i can not connect to my pfsense and have no internet.

          when i connect the wan interface ADDITIONALLY to the network side, i can connect to pfsense and internet!
          i have test it, i can disconnect the lan cable and have access and internet :D …when wan addiotionally connected to the switch ;)

          i want no bridging! i want to access wan / internet from network client

          the default gateway on wan is the router 192.168.10.4
          and the gateway is online!
          my firewall rules are allow all for testing
          i use pfsense 2.0 beta 5

          my routing table:
          default 192.168.10.4 UGS 0 8514 1500 bce0

              Ähm,

              pfsense is a routing plattform. A router connects two or more DIFFERENT networks. Your network on WAN and LAN are both the same. They are both 192.168.10.0/24

              On the WAN side you could use 192.168.10.0/24 and on the LAN side use 192.168.20.0/24.
              On the WAN side NAT must be enabled or you have to enter a static route for 192.168.20.0/24 on the router which is DIRECTLY connected to the internet. I mean this router which has the IP 192.168.10.4.

                    this really good! its godlike ;)
                    thanks for this example….
                    my mistake was the same subnet for lan and wan....thats stupido

                    i want to distance from bridging and ta-ta-ta its perfect -> THANKS phpzilla and THANKS Nachtfalke!!!

                    to do list:
                    other subnets for lan and wan
                    one route: from lan to gateway router on wan
                    firewall rules all access
                    thats all!

                    one question left:

                    before i had bridged interfaces (wan / lan)
                    and this was like a tranparent firewall i think.....i had to only set rules on lan tab for access or denied things on wan and lan!
                    yet? can you explain me how is it managed in routed pfsense modell

                    f.e.
                    have i to set wan rules only in wan and in lan i need only : source lan subet access to any ?

                    thanks for help

                      its seems like that wan rules tab is ignort…..?

                      when i set in wan firewall rules block any any any any any
                      and i set lan rules pass icmp for all

                      i can ping www.google.de

                      only when i block it in lan tab, i cant ping google.

                      therefore i have to only set the lan rules tab ?

                      is it right?

                      thanks

                        You have to set the rule in the right direction:

                        If the direction is from LAN to WAN, for example a Client should not connect to or ping google, then you must enter a LAN rule.

                        If you want, that someone from the internet/WAN should be ablte to connect to your LAN (Webserver, E-Mail-Server) then you must enter a WAN rule.

                        Remember: NO rules means everything is BLOCKED.
                        In general you do not want that someone from the WAN/internet should be able to connect to you LAN, therefor there should be no rules on WAN tab.

                          hmmm,

                          have one more question.

                          when i added a second gateway…..

                          can i set a second static route with same network but other gateway?
                          this strange....one way, two gateways :??

                          i have only one lan but two isp gateways.....all user should use the first gateway and one user the second gateway.

                          thanks for help

                            Yes, you can. For every rule you could specify a gateway.

                            If you have more than one WAN, you should read more about "Load Balancing", "Multi WAN" and "Failover". I think this could be interesting for you.

                            REMEMBER:
                            The firewall rule take effect from top to down. The first rule which matches will be used.

                              that's policy based routing, you can make a firewall rule for this and select the appropriate gateway to use when a packet comes in from the one user.

                                f.e.

                                routing

                                192.168.10.0/24   192.168.20.4    WAN
                                192.168.10.0/24   192.168.30.4    WAN2

                                and then in firewall LAN tab (top entries are dominating) one entry for this one user, how should use gateway two (wan2), with gateway entry to wan2

                                is it right?

                                AND…

                                load balancing...thats intressting yes right!
                                is it for two internetconnections....like trunking?

                                thanks a lot for your professional infos !!!!

                                  For example, if you would like, that Host A with 192.168.10.25/24 should be routet over WAN2 it could look like this:

                                  pass 192.168.10.25 * * * WAN2        This is for Host A over WAN2
                                  pass 192.168.10.0  * * * WAN1        This is for all Hosts from 192.168.10.0/24

                                  Load Balancing could be used for 2 or more interfaces. Its not really like trunking, its more like Bonding.
                                  Seach the forum for Failover, Load Balancing and Multi-WAN. Check the pfsense docs, too.

                                    ok thanks nachtfalke!
                                    i will try this!

                                    i found good tutorials for load balancing and failover….

                                    but there is a difference in it!
                                    some make it with a bridge between the wan connections and some not.
                                    what is the better way ?

                                    thanks for help

                                      Sorry. DOn't know when to use this in bridge mode.
                                      I use it without bridge and I think this is the normal way to use Load Balancing. Perhaps there are special scenarios which need another configuration.
