WNDR4000 firewall issue

[jimbob77]

Hi everyone,
I recently purchased a WNDR4000. However, I have an issue with it, I am unable to setup port forwarding only for specific external IP addresses.

I need to only open certain external IP addresses for SMTP. On my old router (Netgear DG834G) I could do this, but on the WNDR4000 it only seems to allow me to add private IP addresses.

Any ideas? It's causing me quite a headache as I don't want to allow any access to SMTP from the outside world, my e-mail goes through an e-mail provider (Messagestream) to an Exchange server at my workplace. As it stands, in the event viewer I see lots of 7003 errors coming through with weird e-mail addresses in the error message.

Thanks

Jon

wndr400 is not wired gateway. it is wireless/wired N router
