I'm not sure how elementary this is, but here is the scenario:
We switched ISPs not too long ago, our original configuration was a C2600 router and the 7507 router both had a PPTP tunnel between this site and our Washington offices.
We're currently trying to get the 7507 Router to talk to the newly installed 506E firewall that is installed here at this site. My contact in Washington tells me the 506E doesn't support PPTP and that the 7507 doesn't support the new AES encryption schemes, so we're stuck. Is this really the case? What I need to do is basically allow a PPTP tunnel between the 7507 and the 506E, note it's not connecting to anything behind either device, the 506E and 7507 are both endpoints. Is there a possibility this can't be done?
The old Cisco router basically had an interface called TunnelX with the IP source of our old router, tunnel destination on their end and ACLs to allow access through to their internal IPs.
Sorry this sounds so vague but I'm at a loss as to where to start...
