Help! I have 2 877 routers connected using site to site vpn over adsl links. Everything seems to work fine (ping/telnet etc) except remote desktop will not establish a connection back to the main site and the 2003 Terminal server. There are no firewall issues etc and hopefully a clue for everyone is I can get 2 laptops to connect with rdp from the remote site but only if they have the cisco vpn client installed on them (other machine without vpn client doesn't connect).....something linked with DNE? MTU or MSS but do I have to make changes to both routers or only one?
Also HP 3800n printer at remote site will not work but I can ping it on the network and I can even http to the maintenance page it has and yes I can telnet to it on port 9100.
Arrgh!! Thanks for the help - I did think that was the problem but now I've changed the mss to 1300 on both routers, the rdp has stopped working completely (with and without the vpn client installed) Printer does seem to work now though!!
Testing tunnel still comes back with add "crypto ipsec df-bit clear" to vpn interface but I have added this to both routers.......
We have configured the outside and inside Interface with official ipv6 adresses, set a default route on outside Interface to our router, we also have definied a rule , which also gets hits, to permit tcp from inside Interface to any6.
In Syslog I also se...
