Cisco 878 Router Configuration. Help!?! 1

[racoony]

We have just installed a Cisco 878W at the office. So far 5 PCs are connecting it and all use the same public IP x.x.146.237 to access the internet (same as the router dialler interface). Internally, all PCs are on the same Vlan 10.10.10.1-255. The gateway to the router is at 10.10.10.1
All fine so far. But now....?
We are in the progress of setting up a webserver at the moment(Vlan: 10.10.10.11). We can access the same already via Remote Desktop via x.x.146.237, but we have problems assigning any of our other public IPs to the server (x.x.146.238-243) What we need now is to allow access to the server from the outside via http/ftp.

Not sure if it is NATTING or Routing specific. I am not really an expert...

Help is therefore highly needed and appreciated.

Thanks for any help

..go ahead and post your running config..

...and you will have to NAT
...set up access-list to allow 80/21
...and map outside ports 80/21 to internal server ip address

...below my router setup where i'm hosting 80/21

ip nat inside source static tcp x.x.x.x (internal server IP) 80 interface Dialer1(outside interface) 80
...above is my port mapping outside port 80 to internal server ip address and its port..

access-list 111 permit tcp any host x.x.x.x (my_outside_ip_address) eq www
...above is access permiting

http://www traffic

to outside interface..otherwise it would drop there
..hope this helps

Thanks a lot for your help. Clearly, I have forgotten the
following string (access-list 111 permit tcp any host x.x.x.x (my_outside_ip_address) eq

http://www).

It is working now.

Many thanks again

This was very informative. I have a problem somewhat related to this. All of our public traffic can get to our servers with no problem, but all our private address (local machines) cannot get to the server, instead they get a username and password prompt for the router.
