Gateway Switch Not Allowing Communication Between Interfaces

[Quada]

When I change the gateway on my LAN rules from (IPv4 * LAN1 net * * * ***** none )    to      (IPv4 * LAN1 net * * * WAN1_DHCP none )  I lose connectivity to all other interfaces (other than WAN).  For instance I cannot access a server on a guest network.  When I change that gateway option back to default, I regain connectivity instantly.  I have tried matching the gateway specification on all interfaces but that didn't fix the issue.  I have also tried to remove all other gateways, only leaving the default (WAN1_DHCP) but the issue still persists.  This is repeatable on other interfaces as well, i.e. GEUST2 to GUEST1.  The allow_all rule is the only rule on the LAN interface other than the anti-lockout rule.  Again to reiterate the only option changing is the specifying the gateway from default to the only option available.  Any ideas on what to try?

Well how are you going to access your other interfaces if your sending all data out your wan?

If you want access to other interfaces on pfsense, then your going to have to put rules above that rule that allow access to those networks before you shove all traffic out a specific gateway that can not get to pfsense other interfaces.

Rules that match traffic to send connections out a specific WAN can cause local or VPN traffic destinations to exit the firewall WAN rather than following local routing,

This first statement made me go d'oh! Thanks, this was a very easy fix!
