Hello James,

Proxy ARP has been setup the entire time for my 2nd WAN IP ( And it's a straight DSL
connection (no PPPoE) and it's bridged (with the equipment onsite). I have a total of 12 IPs off it.
4 going through the firewall, and 2 others not. 6 not used.

OK, so I added an Inbound NAT entry using 2nd WAN IP interface. So, under Inbound NAT, I see the IP
listed as (ext.: with ext. port range of 80 (HTTP). If I go to rules, it's
been added automatically. Now, I login to another machine across the internet, and attempt to test
HTTP. No luck. I don't think this is a TTL issue, since with my older firewalls, if I activated an
IP, it was immediately available.

Any other ideas?

Thanks for your prompt reply,

Depending on your ISP you may one of the following issues:

1) You need Proxy ARP enabled. (I have a client that just did you are
doing. He has a PPPoE DSL line and needed Proxy ARP.)

2) Your ISP's may have extra long TTLs on their gear. You may just need
to reboot your ISP/s modem/router or wait for the TTL to expire. (if the
gear is upstream from you waiting may be only option - it will work
