      No.  I meant from inside.  Usually when TTLs expire in your situation you have a routing loop.

      Traceroute to .166 from .201

          You have something configured wrong.  What's your IPV4 routing table?  What are all your interfaces configured like?  I don't know how secret you think your IP address is but it's probably getting pretty tedious masking it.

          What interface is configured as .1?  What's its netmask?  I'm guessing here.  you're going to have to figure out why pfSense keeps routing back to .1.

            Just referenced your diagram again.  .1 is your ISP gateway.  That doesn't make any sense because traceroute hop1 should be the pfSense interface facing that segment.

            ETA: Hmm.  pfSense is invisible in my traceroutes.  But only when I NAT.

              i hear ya… i've been poking away at this for some time too...

              i don't think this will help... but when i did test at 5am using route only platform, all subnets could cross talk with no problems...

                Just forget about Route only platform. It will not do what you need.  It also turns off all firewalling and makes all your public IPs wide open.  What you're doing isn't that complicated.  I think you got a little clicky clicky and have something in there that's wrong - somewhere.  What are your NAT rules currently?  What's your IPv4 routing table?

                    See those two routes for 216.185.64.6 and 216.185.75.161 with a gateway of 216.185.75.1?

                    Those (particularly the 161) are probably your problem.  Somewhere pfSense has been told to send everything destined for 216.185.75.161 out to your ISP's .1 address.

                      the only places i can think of that happening would be system:gateways and/or firewall rule interface gateway set to netoptiks… with out that there it wanted to route out isp1...

                        Without that there it will route out whatever your default gateway is.

                          ka, so we've come to a couple ideas where the possible problem may be…

                          i'll make changes to .160/27 so that subnet has gateway 161 and not 190,

                          other

                          maybe bgp...

                          will post in morning with resaults from subnet restructuring, and if that don't resolve, presue the bgp...

                          anyone else with any ideas please feel free to jump in...

                          Thank you Derelict for the time u spent... huge help in long run... :) solved my VIP issue...

                            The only way that should make any difference is if something on the LAN thinks .161 should be the the default gateway.  Like I said in the PM, there's no reason not to use .190 as the interface address/gateway as long as everything on the LAN knows that's the case (just like with .161). Most people use the first IP in the subnet but that's just convention, not a requirement by any means.

                              SOLVED by accident….

                              interface settings: IPv4 Upstream Gateway: changed from none to isp2 gw

                              and

                              changed firewall rules for subnets from isp2. "gateway" was set as netoptiks (isp2) changed back to default....

                              after doing this was able to get communication between lans(subnets).....

                              4 months banging head on desk... :)

                                possible related issue here….

                                so after thinking everything was all good, i saw something strange and doesn't look right....

                                from a subnet on isp2 (blue) i ran a traceroute and this was the resault...

                                216.185.75.190 should not have routed out 67.69.244.253 (<-belongs to isp1 pink) but rather should have stayed in isp2 gw which is 216.185.75.1…

                                any suggestions????????

                                  What are the firewall rules for the interface on which 216.185.75.190 can be found?

                                  Which WAN is set as your default gateway?

                                    default wan is isp1bell (pink)

                                    when i set firewall rules for blue(isp2) subnets to default i can cross talk but wrong outbound, when firewall rules set gw as netoptiks(isp2) they route outbound proper but can't cross talk…

                                      Seems like it shouldn't do that.

                                      You might try creating something like a local_nets alias, put the /24 in it (or whatever local networks you want to "cross talk" with) and put a pass rule on each LAN interface from "THAT_INTERFACE net" to local_nets with the default gateway (*/none).

                                      Follow that with a pass any any any rule with the desired egress gateway set.
