Hi I got a huge problem with routing on my ISA Server 2006. I got it working when I do a ping or normal tracert, see example 1. But when I try to "simulate" web traffic is ignores the route and just go out on the external network. WHY?

FYI
EXAMPLE 1
C:\Documents and Settings\lla>tracert 192.168.89.1
Rute spores til 192.168.89.1 over et maksimum af 30 hop
  1    <1 ms    <1 ms    <1 ms  x.x.dk [192.168.100.14]
  2    <1 ms    <1 ms    <1 ms  192.168.100.1
  3    10 ms    12 ms    11 ms  192.168.89.1
Sporing fuldført.
 
EXAMPLE 2
C:\Documents and Settings\lla>tracert 192.168.89.1 80
Rute spores til 0.0.0.80 over et maksimum af 30 hop
  1    <1 ms    <1 ms    <1 ms  x.x.dk [192.168.100.14]
  2    <1 ms    <1 ms    <1 ms  y.y.y.y.dk [123.456.789.123]
  3  y.y.y.y.dk [111.321.123.213]  rapporter: Modtagernet ikke tilgængeligt.
Sporing fuldført.
C:\Documents and Settings\lla>

I'm not sure the test you're using is valid.  TRACERT only does ICMP traffic, so the "80" value you've put at the end does not simulate web traffic.

To determine if a TCP listener is repsonding, I typically use "telnet x.x.x.x port"

ie:  telnet 192.168.89.1 80

Can you explain the problem you're encountering?  Typically, routing doesn't have to be adjusted in a basic ISA implementation.

Yes you are correct, the tracert test is not valid. Thanks for the tip.
