My setup is as follows :-

ADSL(Dialer0)---> 2811 ----> Fa0/0.x

I have a pool of 16 assigned IP addreses

I have internal networks on various VLAN's, and they are all Nat'ed to

one of the assigned address. (Say


I also use static nat entries to NAT servers to public IP addresess.

(i.e mapped to 212.x.x.117)

Now, the problem I have is this :-

My staticly nat'ed web server can be reached from the internet fine.

But when I try and access 212.x.x.117 from my internal network, it fails.

I need to be able to access the web server using its public IP address from within. I can access it using its internal address, but that does not help me, as I need any requests to appear as though they come from a public IP address.

Any ideas what I might be doing wrong ?

Or any hints on how I can better nat public servers ?

I am currently using

ip nat inside source static <src> <dest> with a route map so that VPN hosts are not nated.
