Hello,
I configured this router to use NAT overloaded to get access for any computer on the LAN to Internet.
I configured (I thnik) a static routes to get in the LAN WebServer from outside, but there is no effect, I can't reach the server. Could help please:

this is the debug info of "debug ip nat detailed" (the address 217.x.x.217 is not the real address, I change it in this letter only):

Hello,
Resolved!
I put this for future information for who has similar problem:
finaly I resolved this problem. The problem was not the configuration of the 2811.
The problem was the default gateway of the web-server computer. In my case I have two routers - 192.168.0.1 and 192.168.0.2. The default gateway of the web-server is 192.168.0.1 but the access to it is true 192.168.0.2 (inside lan address). Then when the remote client try to connect via router X.X.X.X - 192.168.0.2 the web-server try to respond via 192.168.0.1 but there is not tcp connection this way. The connection is opened by remote cliente via 192.168.0.2.
When I put the default gateway to 192.168.0.2 everythink works fine.
Thanks everybody who's try to help!!!
Regards, Kiril.
