Hi Everyone,
I've searched and worked on this for the last 2 days... still dont know what the problem is.

Error:
Unable to determine external ip address

My friend cant connect to me, I cant connect to him.
We can connect to public servers.

I have opened up port 34197 (single port fwd) over UDP
Double checked local firewall

Tried using a port mapper, that didnt work.

Anyone have magic insight into what I'm doing wrong?

Jesus, that response made me feel like I'm dealing with my QA department. Figure out what I want to know!

Make a useful title... check (at least I think)
-Describe the problem as best as you can... Outside of the info provided, do you want to know how I specifically setup port forwarding?
-I added 12035 and 12037 based on the log also with no luck.

Provide Attachments... you could have said "hey we need X"

Thanks for any help.

Your port is not static, this is either a router or ISP issue. See: 47110 and 48157.

Clearly my search foo isnt anywhere near as good as I thought.
The only info I could find on port randomization is for Pfsense. Any idea what Linksys refers to it as? All I keep getting back is port forwarding info.
