Hi
I've migrated a linux firewall to a 2.3.3-RELEASE-p1 pfsense.
The old configuration was with 2 interfaces connected to adsl routers and an 
interface for the lan. Was configurated also a GRE VPN with an alias IP on this 
LAN network so on the same LAN  coexisted two networks
192.168.1.0/24
10.7.13.0/24
where the first was for all desktop clients and the seconds for the servers. A 
server have a interface on the LAN with Ip 10.7.13.1 and a alias on the same 
interface with 192.168.1.6.
When a client is connect to this server, sends packets to the firewall and the 
firewall resends  that to the destination server. The server receive this 
packets and reply using the same interface but contact directly the client 
with IP on the same net. Before with linux this was not a problem but with 
pfsense, a statefull firewall, this is not more possible. Now i've an 
asymmetric routing without a routing so I cannot use the tips present at this 
page https://doc.pfsense.org/index.php/Asymmetric_Routing_and_Firewall_Rules

How can I to do?

Best regards
Claudio M.
