How to set up the 881 to do the same as our WRT54GS?

We have a Cisco 881 router and we can access it using the CCP 2.3. With this router we can surf internet with no problem and we want to replace it with my old router Linksys WRT54GS, but we need to open this ports on the 881:

Linksys WRT54GS configuration under -Applications & Gaming - Port Range Foward:

Application Start End Protocol IP Address

Apache 80 80 Both 1.100.100.240 (this is our web server ip)

MySQL 3306 3306 Both 1.100.100.240

FTP 21 21 Both 1.100.100.240

SSH 22 22 Both 1.100.100.240

Can anyone pls tell how to set up the 881 to do the same as our WRT54GS?

Tips:

if you can connect to router with telnet, you can use configuration below.

for example;

wan ip = x.x.x.x

#conf t

(config)#ip nat inside source static tcp 1.100.100.240 80 int x.x.x.x 80

(config)#ip nat inside source static tcp 1.100.100.240 3306 int x.x.x.x 3306

(config)#ip nat inside source static tcp 1.100.100.240 21 int x.x.x.x 21

(config)#ip nat inside source static tcp 1.100.100.240 22 int x.x.x.x 22

(config)#end
