Port Forwards

We have an UC 540W and would like to do port forwards

3389  to 192.168.10.10

3388  translated thru the router to port 3389  at ip 192.168.10.11

Port 25 needs to only allow traffic from network 64.18.0.0-64.18.15.255  (or 64.18.0.0/20) (or 64.18.0.0 mask 255.255.240.0)

I am unable to do this thru CCA 2.2.6.  Could someone let us know how to get this done?

Re: Port Forwards

For port forwarding, you'll need something like:

ip nat inside source static tcp 192.168.10.10 3389 3389

ip nat inside source static tcp 192.168.10.11 3389 3388

To allow SMTP traffic from 64.18.0.0/20 to your outside IP address, you need something similar to:

access-list 101 permit tcp 64.18.0.0 0.0.15.255 host eq smtp

interface FastEthernet 0/0

ip access-group in

You would also need a static nat statement such as the above to forward SMTP traffic to an internal address.

Hope this helps.
