The last step in our new equipment installation/upgrade and I’m absolutely stumped.
Here’s what we have going on… Two Cisco 2801’s with identical IOS’s and perfectly mirrored configs, one on a cable conection and one on a fiber connection, ipsec vpn up and connected between them through the internet. I can ping, telnet, and remote into the LAN(s) from anywhere.
Remote Desktop works, to a certain point. If Ii am on the local lan, I can RDC between the computers, both ways. If I remote from the internet into one of the LANs Ii can RDC, and if I remote from one lan into the other LAN I can RDC… but I CANNOT RDC using only the ipsec tunnel established between them.
I’ve been searching up and down the internet for solution but most come back to MTU problems… it can’t be MTU on the 2 pc’s because they can remote locally, and through the internet… so those mtu’s are fine…
however, if I look on both my routers, no mtu is set, and it won’t let me configure one, and I’m assuming it’s because I’m not using DSL or T1 with any type of encapsulation.
This has been driving me nuts for over a week. Someone help me, please!
