Only permit one Web session conection.


Hi I configured the cisco to get with a static NAT to reach my internal WEB server at adress, from outside. It is well configured. I have a registered domain , and pings works allways ,(from outside the lan ) reach the router. The problem come when I use either IE or firefox, write my domain I can open the WEB page properly. But is occurs only one time.

If a close the session and try  again, I can´t. The page is in blank.!! or open try to the web from another computer , I can´t see it.

The only way is to stop / start the web service and I can access again, buy again only one time... !!

To check if was a problem of WEB server I installed apache and IIS .. so there is not a problem with the WEB software. Internally in my LAN  I can open the WEB page properly , not only one time..

is something missing into the cisco router conf to cause this problem

There is no firewall at all to avoid drop problems.

any idea??help ??

thanks a  lot mates!
