If these two offices interact a lot, it might make sense to look into using a VPN tunnel. Besides the security, the VPN devices will abstract all of the hops and retain your original IP. Then, as long as SOME data is flowing, your ADSL router should keep the connection open. Our T1 routers have the built-in VPN tunneling, as well as little Linksys boxes we use on xDSL and cable connections. They seem to work pretty well, and we have the added security of tunneling everything. It makes our Wide Area Network much cheaper than the days of frame relay to everywhere. That would also fix the MAXPERIP issue you're seeing... ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
