Why is this happening?

Hi!

I've got the topology:

[LAN1]--|VPN box 1|--Cisco1800--..Inet..--|VPN box 2|--[LAN2] | | -----------IPSec tunnel------------

Cisco1800 is a NAT router with one public IP, say W.X.Y.Z. VPN box 1 has a private IP, and VPN box 2 has a public IP. There is a tunnel established between the vpn gateways. This is working fine, and I have a connection between LAN1 and LAN2.

But I don't understand one thing: every connection tha I make from the Internet to the router's public IP is forwarded to the VPN box 1; suppose:

I telnet to the W.X.Y.Z, and I get the VPN box 1 management console. I open a web browser and go to https://W.X.Y.Z and I get the VPN box 1 WWW interface. Why is this happening?

I'd like to forward only VPN traffic to the VPN box 1, which are IKE and ESP protocols. How can I do that?

I attach my router config below.

Thank you, Tomasz Grzelak
