IPSec tunnel between Cisco 2801 and PFSense

I am running an IPSec VPN tunnel between a 2801 router running the c2801-advipservicesk9-mz.124-15.T9.bin image. The other VPN endpoint is a PFSense firewall. The tunnel is established. The issue I'm having is that with the tunnel up we were not able to RDP across the tunnel to our Windows server.

One of our techs added the command "no ip icmp rate-limit unreachable" command and RDP works, however now accessing computers across the VPN using VNC or VMware Virtual Infrastructure Client is failing. It seems more like packets are being dropped rather than no traffic making it at all.

All of these protocols work internally and when published to the web.

Re: IPSec tunnel between Cisco 2801 and PFSense

This is now showing up with running ssh over this tunnel. I can get the initial connection, but certain commands are not going through.

Issue was related to active directory and WINS.
