New ASA5505 owner, having an issue or two

[PCTechNerd]

Hello everyone,

The company I work for recently purchased an ASA 5505 to replace our crappy Netgear Firewall/VPN router (was having memory leak issues inherent to the specific model).

I have it set up and working, and all of our stations can access the internet, but when trying to use WLM remote assistance to connect to a colleague's computer who is out of state, it just hangs, and the ASA 5505 gives the following message in the log:

2 Jan 25 2008 14:57:27 106001 66.179.217.80 64.115.102.90 Inbound TCP connection denied from 66.179.217.80/443 to 64.115.102.90/10048 flags PSH ACK on interface outside

I'm still a noob when it comes to configuring the ASA 5505, so any help to resolve this would be appreciated. here's the running configuration:

Check this out. It is a description of the error.

I believe Remote Assistance relies on UPnP for port forwarding and can't get through the router without it.

I appreciate your comment but it doesn't help me. I need a resolve, not an explanation of what it is. I don't mean to come off as rude so if I did, I apologize.

It won't work - The ASA doesn't support UPnP.
