Hello, I recently decided to give ipf and ipnat a try, previously I had always been using ipfw and natd. Since switching over I can no longer establish a VPN tunnel from any system behind the gateway. I did 'ipf -F a' to flush all rules but I was still unable to connect so I think it's a problem with ipnat? Also my redirect from ipnat doesn't seem to work either. These are the only ipnat rules I have: (fxp1 is the external interface) # ipnat built in ftp proxy rules map fxp1 10.0.0.0/24 -> 0/32 proxy port 21 ftp/tcp map fxp1 0.0.0.0/0 -> 0/32 proxy port 21 ftp/tcp # CVS Server on Fileserv rdr fxp1 0/32 port 2401 -> 10.0.0.2 port 2401 tcp/udp # nat all out going traffic on fxp1 from internal lan map fxp1 10.0.0.0/24 -> 0/32 I can post my firewall rules too if that would help, however with NO rules set it still didn't work so I don't think that would help.. (I'm using the klm which is default to accept?) Thanks! J.
