We have some 871's which will not pass telnet through the router, to the devices on the other side. Some will, other won't. Config's are identical, except for where the DHCP pool (dns-server) is getting the information. The one in serious trouble ...

Using VPN on DSL, with GRE tunnels, I find on 1/2 of the routers I cannot telnet through the router - even with the same config. It stops cold, while others pass telnet fine. What's the answer folks?? Jeff
