Wrath of the 1160

[Arkos]

Alright here's my problem.

I'm currently getting a constant 1160 error.

Connection type: DSL

I was playing it fine until two days ago when it LDed me and I haven't been able to get on since.

I have done all of the following:
-Installed/Uninstalled Norton's Personal Firewall 2003
-Rolled Back my system until the day after I installed FFXI
-Called my ISP, all ports are open that FFXI uses
-Called Playonline, they say it's a port problem, or a dsl firewall
-Norton Anti-Virus hasn't shown anything wrong

Things I have noticed while snooping around trying to fix this problem:
-I can't get into the advanced option of my dsl connection (Odd thing, it dials into the server instead of straight connecting like a cable modem).
-When I try to install a new connection (Under network connections). If I don't put the firewall up, the icon for the connection vanishes instantly. If I disable the firewall after creating the connection, it vanishes instantly.

Im starting to run out of ideas here, anyone here extremely good with this kinda stuff that can help me here?
