Hi all,

I've search many topics but didn't find any solution so i hope someone will have an idea to help.
I try to replace my old symantec FW by ISA 2004 , so i take up all the rules in ISA.

I have 3 NICS :

- one connected to internet : 80.xx.xxx.xxx/29
- one connected to a corporate network : 172.29.22.1/24 no gateway
- one connected to internal network : 10.95.0.0/24 no gateway

The default gateway for internet is 80.xx.xxx.xxx and i have add a route to corporate network : 10.0.0.0 255.0.0.0. 172.29.22.2
There is a cache DNS on the ISA Server and a DNS with forwarder (corporate DNS) on the internal network.

Everything runs fine : PC on the internal network could access Internet, we could send & receive mail from corporate and from internet.

My only problem is the access to 2 website on the intranet, the weird thing is that i could ping the 2 websites but when i try to acces with a navigator i received a 10060 timeout error.
When i trace the IPs of the websites (10.20..xxx.xxx and 10.64.xxx.xxx) it goes to the end but there is 5 jump with a timeout error.
When i trace the same IPs on my old FW there is no timeout and the 5 jumps above are in fact FQDN.
I guess there is a problem with name resolution , but i don't know how to handle it ?
Great thanks in advance to anyone could help.

Edit: I forgot to tell that i've tried bypass the proxy like it's explain in the artcile on this site but stil have a 10060 error.
