Nat issues.

Hello. I have a cisco 2811 router with an adsl connection.In the local LAN there is a Linksys load balancer which connects the local lan with the router.However there is a server which connects directly to the router and i want to be able to forward some ports to this server.The router ip is 192.168.10.1 the linksys ip is 192.168.10.2 and the server ip is 192.168.10.213.I want to forward port 2000 and 85 to be sent to the server and not to the Linksys (local LAN).There is already a NAT translation for internet access.Any ideas how can i do that???Any help will be welcome.Thanks in advance.

Re: Nat issues.

Can you post your current template so I can work from that ?

Basically, you need to create an ACL and then a nat source list.

access-list 100 permit tcp 192.168.10.213 eq 2000 any

access-list 100 permit udp 192.168.10.213 eq 2000 any

access-list 100 permit tcp 192.168.10.213 eq 85 any

access-list 100 permit udp 192.168.10.213 eq 85 any

ip nat inside source list 100 interface [external interface] overload

Re: Nat issues.

Hi,

Or like this:

ip nat inside source static 192.168.10.213 172.16.10.X

or

this

ip nat inside source static tcp 192.168.10.213 2000 172.16.10.8 2000
