Minor networking question.

[nath]

Hiya,

I've got a dynamic DNS external address that I've set up for accessing various functions of my computer externally. This works fine, but I can't access it by using the external address internally - that is, when I'm on my Netgear router. If I use my BeBox I can and I vaguely recall there was a name for this functionality that clearly my Netgear lacks. My BeBox is having other issues and I'm planning on buying something new or perhaps trying a custom firmware for the Netgear so need to know what ability to look for.

Anyone got any ideas?

Nat Loopback or Nat Reflection I think.

That's odd. My DG834 happily routes traffic from inside, addressed to the DynDNS IP and NAT'ed ports (eg: 25, 143), back into the internal network. It *doesn't* work for ports that are forwarded by UPnP requests though. I've not tried the DMZ options...

should say: running firmware 3.01.31, since the latest version (3.01.38) has severe problems: DG834v2 Firmware v.3.01.38 Woes. - NETGEAR Forums

Ah, slightly different router for me - I'm on DG834GT. Still, that's certainly interesting - I'll have more of a fiddle rather than just giving up and replacing it.
