Howdy,

A LAN Extension is being installed which will join our remote office and the hosting site. A router won't be in place until we've have our MPLS circuit installed. Just wondering is it possible to use the GWs to handle routing between the two sites.

The idea is to make it so the Gateways send LAN traffic through the LAN Extn and internet traffic through the external interface. Below is what's running at both sites.

Site A - Hosting Site
R62 on SPLATPRO
eth0 - External IP - 192.168.1.1
eth1 - Internal LAN IP - 10.10.6.1
eth2 - DMZ - 10.20.6.1
eth4 - LAN Extn IP - ???

Site B - Office
R62 on SPLATPRO
eth0 - External IP - 192.168.2.1
eth1 - Internal LAN IP - 10.10.7.1
eth3 - LAN Extn IP - ???

Rule Base for VPN
GW-to-GW (All Gateways)
Site-to-Site (All Protected Networks)

Would either of the following work:
Setup eth4 (HS) with 10.10.7.2 and hide the 10.10.7.0 LAN behind it and then setup eth3 (Off) with 10.10.6.2 and hide the 10.10.7.0 LAN behind it.

Setup eth4 (HS) with 10.10.7.2 and NAT it to a 10.20.6.2 IP address and then setup eth3 (Off) with 10.10.6.2 and NAT it to a 10.20.7.2 IP address.

If it won't work what will....besides a proper router.....

Cheers.
