Ok, updated the 2750Vn to the latest firmware (1.5.1 - which isn't available via draytek.co.uk yet) and it's got support for Multi-NAT now. Not quite as flexible as the old 2800Vg, but looks like it's sufficient for my purposes.

Cheers,

Turns out it still doesn't work quite as I expected and would like.

While -incoming- packets are routed correctly, all outgoing packets go through the main NAT IP.

Incoming:
Public IP1 -> NAT for LAN
Public IP2 -> routed to PC1

Outgoing:
LAN -> Public IP1
PC1 -> Public IP1 **** Not as expected!

I would like outgoing packets from PC1 to go via IP2.

I've spent a lot of time trying to work this out. This was trivial to set up on my old 2800Vg.

Any suggestions welcome,
- Micha.

Hi Micha,

I guess whats missing in Vigor2750 fw, for this kind of setup is "Address Mapping" feature, which is already available on Vigor2820/2830/2850/2920 models. Where we can setup a LAN IP to use a specified WAN Public IP.

Since Vigor2750 is a Linux based model (different from Vigor28xx/29xx) , it may not contain already this feature.

I suggest to request this feature for DrayTek.

Hope this helps,

regards,

Hi,

hope some will check out this forum post. looking for a solution to my problem, i too have a static ip block.

i have tried some of the things listed, but with very little luck.

i am on BT Infinity business, and have been given a block of 5 static ip addresses. i cant seem to get the static ip's to work. there is a wan ip alias section in the pppoe settings. which none of the user manuals seem to have any information about. I'm using a draytek vigor2750n.

dose anyone know if what i am attempting to do is possible with the bt service.

or if i should just give up. i'm just trying to get the statics to work so i can rdp to my home server.

thanks,

carl.

No,

well dmz fine. which is not great but solves the issue for now...
