I have a GRE tunnel built between a 1801 router and a 3725. Servers on both ends are running 802.3 encapsulation. If i do a sh ipx servers on the 1801, i see a full listing o of IPX devices throughout the network. The problem im having is, users sitting behind either router can see the servers listed in their explorer and can connect to the servers. They can see the volumnes listed, but can not connect/see contents of the volumnes.
I have this problem too.
