I had a call today from a client stating that one of the network printers at a remote site was not responding to the Head Office print server, yet would respond to individual workstations at Head Office. This company runs two networks (one for external support and one for internal usage).
The main routers for the IP Clear circuits used for WAN connectivity provide NAT services to route across the two networks.
Pinging the printer from the main server produced a response, yet pings from the print server were being lost.
The printer had its default route set to a broadband router (which mainly provides DHCP services and redundancy in the WAN link) this router had full connectivity to the internal network and the the print server was set to have its default network as the support network and to utilise the support router.
Changing the default route on the printer to the main router gave immediate connectivity both from Head Office/remote workstations and the Head Office print server. Perhaps I was being a bit too clever for the broadband router when I initially set up the routing tables.
