2 routers - 2 gateway

[Tan Choh Koon]

Hi,   I had Hub site where I would have 2 units of 1720 router, one is for leased line to ISP and another for the ISDN DDR to remote spokes.       PCs -------------------------------e0--RouterA----------------------- ISP                                   |                                   |                                   |_____e0--RouterB-- Bri0---------------- Telco ISDN     The PCs are on the LAN with Network 10.10.30.0/24 e0 on Rotuer A is 10.10.30.1/24 e0 on Router B is 10.10.30.2/24 Router A will configure with NAT to let PCs with private address to access to Internet Router B will configure to dial to spokes site where the networks are 10.10.50.0/24 and 10.10.60.0/24 respectively.   I want my PCs can access to Internet and the Intranet , so how can I set the Gateway in PCs ??? If the gateway set is 10.10.30.1/24 then it will not able to communicate with Intranet.   Any suggestion ?   Thanks a lot.   C.K.Tan
