*Please can someone give me a nudge in the right direction to help me fix this annoying problem*

All my clients on my internal internal can connect to my webserver on my external interface - but i cannot browse to it directly from my ISA server?

Client 192.168.22.1 --> Web Svr 192.168.7.4 (OK)
ISA Svr 192.168.7.1 --> Web Svr 192.168.7.4 (!OK)

I have the network config as follows

ISA 2000 Std - 2xNics
external iface 192.168.7.*
internal iface 192.168.22.*

ISA is setup to send traffic to a uplink proxy before going out on the internet.

Everything is working ok!
I can browse the internet from my internal network.
I can browse the intenet from my external network (as long as i modify the browsers proxy settings).

On a client machine on the internal interface i can browse to my development website 192.168.7.4 port 80.

On my machine hosting ISA i am unable to connect to this site, however I can ping 192.168.7.4 from my ISA server box but i am unable to telnet through to port 80.

q1) How do i open up the firewall to allow me to do this?
q2) My website will eventually be hosted on port :99 how would i go about setting ISA to allow me access to this port

My basic understanding of ISA is slim - i just need a quick dev env setting up. I have just followed the basic tutorial "http://www.isaserver.org/tutorials/quickstart.html" and desperately need some pointers to where to go now. I have read the other tutorials but dont know what "key words" relate to me.

Any help whatsover is most appreciated.

Can someone just clarify -

"Web Publishing" .. allowing external users to see your internal website.

If this is the case, my problem must be just in routing. I need to send some non-internet related traffic directly to its IP address (but this works because i can ping). Does this imply a firewall problem?

ISA is secure by default and allows access to only a subset of websites, normally windows update and CRL list sites.

You must modify system policy to allow access to other sites, even your internal.

To change the port number you would change your server publishing rule, also nothing that you can leave your internal website on 80, and get the ISA to redirect the traffic to port 99
