This question is about 50% can I, and 50% how do I. First a little background, we're a smaller ISP with an older USR Total Control Chassis (one PRI coming in, quad modem cards, Netserver PRI, NMC). Our internet connectivity is coming in to the office via T1 through an external router (and we have 3 IP blocks coming in through that router, servicing the servers on the LAN, as well as the dialup users connecting to the TC). The Total Control is plugged into the LAN through the LAN port and that's path that dialup data follows out to the Internet. Nothing connected to the 2 WAN ports on the TC at this time. The T1 was in long before the Total Control and so there was never any need seen to change that configuration. For various reasons I'm thinking that now might be the time to retire the external router and rather than go out and pick up a new one, it might be best to just use the Total Control to perform that function... if it'll work. So that's the "can I" part of the question... will the routing capabilities within in the TC work to serve both the servers on the LAN, and the dialup users connecting to the chassis? The second part of the question, "how do I". From the sparse documentation we have around I can see the "set wan0 address" and "set wan0 netmask" to set the upstream IP for the router. I've got "set net0 address" and "set net0 netmask" to change the LAN IP of the TC to match that formerly used by the external router (saves reconfiguring the gateway on all the servers). Now... the ones I'm not sure about... "set net0 routing" "set wan0 routing" "add wan0 <dlci #>" ...what are going to be the proper settings for these in this configuration. The only other info about the configuration of the existing router that I can think might have some bearing is that it is connected to the CSU/DSU via a V.35 cable, and the protocol on the WAN port is specified as PPP, speed of 1544000. And finally routing... we have 3 address blocks... lets say 1.2.3.x, 4.5.6.x and 7.8.9.x The existing router currently responds as IP's 1.2.3.1, 4.5.6.1, and 7.8.9.1 The 1.2.3.x and 7.8.9.x blocks are just routed out to the lan port and service various servers and workstation, whereas the 4.5.6.x block is routed to 1.2.3.5 (which is the LAN ip of the TC) and is used as the address pool for the dialup clients. Now assuming that I change the LAN IP of the TC to 1.2.3.1 (or do I need to leave it at .5 ??), how do I go about setting up the routing to act the same as my existing setup, how do I configure the TC to respond to the other two .1 addresses, and are there any other configuration changes that I'll need to make. Thanks in advance for any assistance you may be able to provide. Thanks,
