Cisco 877 and Port Forwarding

Hello,

I have a cisco 877 with 3 vlans and and atm interface with a bvi interface.

Vlan 2 and 4 : are nat inside. two different subnets

Vlan 3: bridged directly to atm.

BVI1: nat outside. gets its ip address via dhcp.

I have some static nat port translations from bvi1 to some vlan4 hosts.

Everything works fine. The problem is that when I power cycle the router or the dsl (atm) goes down and then up the nat translations stops working. To work I have to erase the translations and create the again.
