can someone untangle this one for me?
We have a sit to site vpn set up with rules in place to only allow specific traffic through.
HQ have made some changes and moved stuff around. We can connect to x.x.x.22 no problems on port 80. We can also ping x.x.x.22 and telnet x.x.x.22 on 1494.
New IP has been introduced. x.y.y.22, we can ping and telnet on 1494 x.y.y.22 however we cannot get to x.y.y.22 on port 80.
From a specific server on our lan we can access x.y.y.22 , this server is not set to use a proxy server.
From the above the problem appears to lie with the proxy server. We use ISA2004 and Webmarshal although I do not see that webmarshal is in play here.
On ISA i can see a rull allowing all traffic to x.x.x.22 , editing this rule to allow traffic to x.y.y.22 does not solve the problem.
Any one know where I should be looking now?
Appreciate all comments,
