Hi I was re-reading this response as i am experiencing problems with my fw-1 on this point: i.e. firewall-1 has to nat to external interfaces which are not in the same network address it belongs ot. fw1:external_interface: 200.10.50.1 And has to NAT-Hide to: 200.40.20.1 and 200.40.21.1 So far: I-ve assigned these addresses to router: 200.10.50.2 200.40.20.2 200.40.21.2 On fw-1 , i ve set a local.arp 200.10.50.1 200.40.20.1 200.40.21.1 Is there anything else I should do? Like adding manually these ip addresses as aliases to external interface or local.arp is enough? This configuration seems to work for intervals and suddenly , fw-1 "loses" its NAT rules on some hosts. Am i missing something?

Set static routes to the alternative external ip addresses on you router, pointing to the firewalls external ip. -or- 2. Set a static arp entry for the two other external ip addresses on the firewall.
