Well, "typical" in that it's just another published service... there's really 
no difference (to me) in publishing that or RDP or whatever as long as you take 
the "proper" precautions...

Regardless, that was exactly it... I could have sworn that I tried that last 
night, but I obviously didn't.  So, right now it's a server pub rule with 8080 
as a custom inbound protocol and is currently all users.  Should I do the same 
thing with Web publishing rule instead so I can set NTLM auth on the listener?

I wouldn't call this "typical" by any means, but neither is this a unique 
request.
I't s possible, but not exactly advisable for Joe Admin. No doubt you're using 
port pbfuscation and auth to keep the script kiddies at bay...
Make sure the rule is set to "requests from from the TMG computer" or TMG will 
try to respond via the routing table instead of the "internal-internal" socket 
map, causing the "non-SYN" log entry.

Subject: [isapros] Publishing proxy listener on TMG
Has anyone successfully published the internal network proxy listener to the 
external network on TMG?  This is trivial to do with ISA/TMG in hork mode 
(single nic) and though I *thought* I did it in ISA with the typical 
external/internal nic config, I can't get it working in TMG.  I'm either 
missing something simple, or it just no workie.

Basically, I want to be able to connect to my TMG proxy from the outside world. 
 Typical stuff.  In hork mode I was doing it just fine and using NTLM auth over 
HTTP with a strong password which is just fine.

I've tried web publishing on an alternate port listener to 8080 on the internal 
interface, but get "non-SYN" errors, even after creating a rule to allow 
External->Local for the proxy traffic, and I get "bad gateway" when I just 
server publish either 8080 to the internal or even a custom protocol.  
Something's just not right.  Anyone?  Beuller?  Anyone?
