port forwarding

[gschertz]

I need to host email, www inside of my firewall. I am using a cisco 1710 router with fw/ids/ipsec IOS. How would I forward specific ports from the Internet to specific host on my internal network?

With a pix I would need more than one IP public address. I am hoping this is not true with the router.

thanks

for ios router,

ip nat inside source route-map nonat interface Dialer1 overload

ip nat inside source static tcp 25 interface Dialer1 25

ip nat inside source static tcp 80 interface Dialer1 80

access-list inbound permit tcp any host eq 25

access-list inbound permit tcp any host eq 80

further, pix is also capable to achieve the same objective.

So by creating the dialer interface with route-map I can use the single ip address assigned to me for both Internet access and forwarding needed ports to specific internal hosts. This looks like it will work. I will test it today

Thanks
