I'm trying to configure an ASG virtual appliance in my home lab with an ADSL modem in bridge mode. I am in New Zealand and the ADSL here is all PPPoA so the DSL modem has to do the login. With the modem in bridge mode this shouldn't be a problem. On the ASG appliance I get a WAN IP address 118.93.42.146 but no gateway is assigned by the DSL modem. I have been using the DSL connection this way with an Airport Extreme and it works fine. In fact if I hook up the ASG to the LAN side of the Airport Extreme the ASG works fine as well but then I have a double NAT configuration. Is there some configuration I'm missing on the ASG? It simply doesn't have a default route. I have checked the box on the WAN interface of the ASG to make it the default gateway. When I do that the default gateway on the WAN interface shows as the same IP as the WAN interface. I've also checked the box in the Advanced section of the WAN interface to Proxy ARP but still no traffic flows out the WAN interface.
The ARP table on the DSL modem shows the ASG WAN MAC address correctly. I know that no traffic is flowing to the DSL modem from the ASG because the ARP table on the DSL modem gets populated when the ASG broadcasts for a DHCP provided WAN address. After 10 min or so the ARP entry expires and drops out of the ARP table on the DSL modem. If I tell the ASG to renew the DHCP on the WAN interface the ARP entry reappears. If the ASG was sending any traffic out the WAN interface the ARP entry would never disappear.
Any ideas would be greatly appreciated.
Cheers,
Jason
