Router: port forwarding problems.

Question:

I want to make Catalyst 3560X  my HTTP-server accessible from the outside (it's located on my LAN).

HTTP-server listens on port TCP 80 on all interfaces, IP address 192.168.112.17/24. (I can ping outside addresses from this machine.) My router - Cisco 2951, here's a part of its config:

interface GigabitEthernet0/0

ip address W.A.N.IPAddress W.A.N.Netmask

ip nat outside

ip virtual-reassembly in

duplex auto

speed auto

interface GigabitEthernet0/1

ip address 192.168.112.254 255.255.255.0

ip nat inside

ip virtual-reassembly in

duplex auto

speed auto

ip forward-protocol nd

!

ip nat inside source list 1 interface GigabitEthernet0/0 overload

ip nat inside source static tcp 192.168.112.17 80 W.A.N.IPAddress 80 extendable

ip route 0.0.0.0 0.0.0.0 W.A.N.GatewayIP

!

access-list 1 permit 192.168.X.0 0.0.0.255

access-list 1 permit 192.168.112.0 0.0.0.255

access-list 1 permit 192.168.Z.0 0.0.0.255

access-list 101 permit tcp any host W.A.N.IPAddress eq www

So I cannot reach the server from the outside. The router responds to pings (ICMP echo packets). I'm entering router's W.A.N.IPAddress in my browser's address field and there's no result. Help me, please!

Answer:

Here is simple config:

ip nat inside source static tcp 192.168.112.17 80 46.45.33.X 80

As WAN IP address for server here you need to use one spare address from your scope e.g. 46.45.33.5 as you have big enough subnet /25.

Also I would not recommend to Catalyst 3560X Price post here real Public IP addresses.
