Tunnel between Pfsense and Cisco

  • Greetings,

    I have an out-of-the-ordinary tunnel setup problem.

    I have set up plenty of tunnels between Pfsense, Cisco, Sonicwall, etc.

    None of that has ever given me any trouble.  This one has me stumped.

    My Pfsense is using 192.168.x.x for it's LAN subnet.  The Cisco box is using 193.x.x.x for it's subnet.  No problem making a tunnel with that, right?  Well here's the kicker.  The Cisco box already has a tunnel going to 192.168.x.x so I can't just connect the two.  To combat that I set up the tunnel using 193.x.x.22 for my side and 193.x.x.21 for the Cisco side.  The tunnel comes right up.  The Cisco box can ping my .22 address but I can't ping him at the .21 address.  What I'd really like to do is just have any ftp traffic that hits the .22 address be forwarded to an address on my 192.168.x.x subnet.  I can't figure out how to do that.  Any ideas?

    Thank you in advance.
