I work with another company with whom we've established a site-to-site vpn. They are moving to a new office. They've acquired new equipment so that we now have tunnels connecting to both locations from my site. At the new site, some of the addresses on my side are unaccessible to them. Connectivity in every other way is just fine. I use the same network object-group for my addresses for both tunnels. No ip addresses overlap.
I'm running PIX 6.3(5). Their old office uses a PIX (version unknown) and their new office uses a brand new Checkpoint NGX R65 module. Has anyone run into this before?
