Nat and routing

Dear all,

i want to know about, Is it possible to Nat and routing on single router. i have 1811 having 2 FA routing ports and 6 switching ports (interface).

currently i am running NAT on this router. FA1 is configured as private ip, and FA0 is for public ip address. i want to add seconday ip address on FA1 to publish my web server.

I assigned a public ip (secondar) on FA1.

If you want publish a web server, why can't you just create another static NAT for the server

Re: Nat and routing

i have 3-5 servers that i have to publish. (web publishing) so thats whay i am asking that.

Re: Nat and routing

Hi Ammad.

I agree with Narayan.Did you mean webpublishing that can be accessed from the outside(Internet)? Have you got a block of public ip addresses from ISP? I meant a different block(Subnet) ip addresses that you assigned to FA1. You can achieve this task by using static nat.

F.e.The ip address of WebpublishServerA is 192.168.1.55 mapping to public ip a.b.c.d

Keep life simple. ;-)

ip nat inside source static 192.168.1.55 a.b.c.d

Added a bit security for your house.

ip nat inside source static tcp 192.168.1.55 443 a.b.c.d 443

Or

ip nat inside source static tcp 192.168.1.55 80 a.b.c.d 80

Hope this helps
