IP TCP Intercept

Hi,

I have Cisco 3640 Router with IOS 12.x. I wanted to configure tcp intercpet for my web server which has ip address x.x.x.x1. I did the following

access-list 103 permit tcp any host x.x.x.x1

ip tcp intercept list 103

After giving this command i was not able to browse my web server from outside. But when i remove the command it was working fine. Also when i add

ip tcp intercept mode watch and

ip tcp intercept watch-timeout 60

The web server is working fine but when i type

sh tcp intercept connections

i am not able to see this connection, when i change the mode ot intercept which is default though i am not able to browse my web site from outside but i could see the connection in the router when i give

sh tcp intercept connections

showing establised but my website is not working from outside.

Can some one adive me how to rectify this problem.

Thanks in Advance

Re: IP TCP Intercept

Hi,

This could be b'cos of the way you have specified your access-list. You might be knowing that for access-list after a permit statement all that comes below is explicit deny.In this case you are denying all other traffic to that host ( IP,UDP,TCP ) except the tcp intercept .

Hope this is the problem.

Regards,

Homin
