      GW_OPT3 	        IPTV 	        255.255.255.255 	255.255.255.255 	Interfaceopt3dynamic gateway
      

      With the script from the cvs server i get:

      
      Name 	   Interface 	    Gateway 	        Monitor IP 	        Description

              I second the request to update the dhclient-script!

              Everyone using T-Home IPTV in Germany is going to have issues if its not updated…

              To clarify this problem:

              T-Home is using vlans to seperate Web and IPTV traffic. The Web traffic is using PPPoE on Vlan 7, the IPTV traffic is using dhcp on Vlan8.
              IPTV is using unicast for the first 10 seconds of the stream and then switches to multicast which is working very good with the new igmp proxy(which is still spamming the main systemlog making it unusable btw!!!)

              The problem which is fixed by the new dhclient script is that the old script sets a gateway to 255.255.255.255 which is useless and causes the first 10 seconds of unicast to fail which in turn makes switching channels very slow because the STB has to wait for the multicast to begin(1-2 seconds...)

              This is a packetcapture for the iptv interface dhcp reply:

              Which results in this:

              @Beerman:

              With the original script i got this for the Interface in

              System:Gateways:

              With the script from the cvs server i get:

              
              Name 	   Interface 	    Gateway 	        Monitor IP 	        Description

              Maybe this informations is useful for you…

              Both scripts however create the same routing entrys so this is aparently not a routing issue…:

                  Will this Issue be fixed in Version 2?

                  I think with the logs and the explanation inside this thread the problem is reasonably  specified.

                  But if you need another tests/logs, I will give it to you.

                  Thx!

                    Its not a dhclient issue.
                    Try this https://rcs.pfsense.org/projects/pfsense/repos/mainline/commits/5766add89187bf47c225f67697e37ca25b0dbc71 or wait for the next snapshots.

                      sorry, this doesn´t fix it:

                      I tried this Build:

                      2.0-RC1 (i386)  built on Wed Apr 6 11:10:23 EDT 2011

                      Your changes are included in this Build:

                      if [ "$new_ip_address" = "$router" -o "$router" = "255.255.255.255" ]; then
                                                      $ROUTE add default -iface $interface
                                                      echo $ROUTE add default -iface $interface | $LOGGER
                                                      # NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it.
                                                      if [ "$new_ip_address" = "$router" ]; then
                                                              echo $router > /tmp/${interface}_router
                                                      fi
                                              else
                                                      $ROUTE add default $router
                                                      echo $ROUTE add default $router | $LOGGER
                                                      echo $router > /tmp/${interface}_router
                                              fi
                      
                      

                      But for the Interface I still got:

                      
                      System: Gateways
                      GW_OPT3 	IPTV 	255.255.255.255 	255.255.255.255 	Interfaceopt3dynamic gateway
                      

                      and I got the same Problems…

                        Can you remove the /tmp/*_router and try dhclient or Save button on the interface page and see if you will get the same?
                        Maybe making sure that a remnant file is not causing issues.

                        Otherwise something is not matching in that if statement.

                          Sorry, no difference…

                          after removing the *_router files in /tmp and renewing DHCP-Lease GW is still 255.255.255.255

                          /tmp(20): cat vr2_vlan8_router 
                          255.255.255.255

                            Can you try by changing that section from

                            if [ "$new_ip_address" = "$router" -o "$router" = "255.255.255.255" ]; then
                                                           $ROUTE add default -iface $interface
                                                           echo $ROUTE add default -iface $interface | $LOGGER
                                                           # NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it.
                                                           if [ "$new_ip_address" = "$router" ]; then

                              Hi,

                              I changed the script to:

                              for router in $new_routers; do
                                                      if [ "$router" = "255.255.255.255" ]; then
                                                              $ROUTE add default -iface $interface
                                                              echo $ROUTE add default -iface $interface | $LOGGER
                                                              $LOGGER "TEST1"
                                                              # NOTE: Do not activate this for all ones address since pf(4) will try to forward packets to it.
                                                      elif [ "$new_ip_address" = "$router" ]; then
                                                             $ROUTE add default -iface $interface
                                                              echo $ROUTE add default -iface $interface | $LOGGER
                                                              $LOGGER "TEST2"
                                                              echo $router > /tmp/${interface}_router
                                                      else
                                                              $ROUTE add default $router
                                                              echo $ROUTE add default $router | $LOGGER
                                                              $LOGGER "TEST3"
                                                              echo $router > /tmp/${interface}_router
                                                      fi
                              
                              

                              You see, for testing I added $LOGGER "TEST1", $LOGGER "TEST2" and $LOGGER "TEST3" in each If, elif and else block.

                              But in System-Log i can´t see any TEST1, TEST2 or TEST3

                                I made a fix that will be in latest snapshots which should fix this by not having a gateway declared from dhcp and so no PBR will be done from pfSense and routes will be followed.

                                Please test latest snapshots and let me know.

                                  This fixed my issue!

                                  Thank you, very much!
