I have 2 firewalls on the 1st firewall port 25 is forwarded to 2nd firewall and from the  2nd firewall port 25 has been forwarded to windows 2003 machine.This is a test setup.same has been done to port 80.when telneting to port 25  I don't get a reply but when telneting to port 80 I get a reply.On windows 2003 firwall too both the ports are open.When I am telneting internally I get a reply on port 25 but when trying from external network it fails. Any ideas why  I can't telnet port 25.

Did you perhaps accidentally only forward UDP from one of the routers instead of TCP?

Can you telnet to port 25 from a machine connected between the first and second router?

If these are cheaper SOHO routers you may have to powercycle, regardless of whether they're "supposed" to take effect immediately, I have found some that will not.

Why do you want it closed? Did my answer solve your problem?  Abs_jaipur's solution is good troubleshooting, except for the fact he can already locally telnet into the Exchange server.

None of these were the answers for my question. As i said to you before that the port 25 was blocked on the 2nd firewall for some reason. SO I asked the moderator to close the question.But felt that the answers given had atleast gained me some knowledge so I gave them the marks.
