Hi everyone,

One of my VPN's from a 1721 to a 837 (ADSL) is selectivly working.
I can ping across it with a delay of about 50ms, i can telnet on the relevent ports to test ica, smtp etc and all is fine.

I cannot get a citrix client to connect across it, although i can with RDP.

I cannot get an Outlook client to connect across it and i cannot browse the network.

any ideas?
 
Hi Gwildfire,

Here's my config for the ADSL router:

The VPN is up and running, it has just started to get picky with what it'll allow through!
