Multiple external IP aliases are not working — What should I be looking at?
If the alias IPs you have defined cannot be pinged from outside, or configured port forwards are not working, it is possibly due to a stale ARP cache issue.
Try resetting the ARP cache on the router in front of the Smoothwall firewall — on some routers this may require a reboot.
Also make sure that the IP addresses used, are being routed to your Smoothwall, and that no other machines are using the same IP addresses.
