Port forwarding to other networks was created by cobranetworks
Hi All,
I have the DrayTek 5510 and would like to have it take over from a crashing Netgear ProSafe FVS338,

Setup here is a leased line, 8 public IP addresses, Netgear ProSafe firewall at IP 192.168.100.200 a L3 switch and a static route between the L3 Switch and the Netgear,
On the L3 switch I have two additional networks at 192.168.1.0 and 192.168.20.0
With the Netgear ProSafe I can port forward from any of the public IP’s to any of the networks on the L3

Example:
Public 84.33.234.2 port 25 to 192.168.1.200 port 25
Public 84.33.234.3 port 25 to 192.168.20.20 port 25

Can I do this with the 5510 or can anyone suggest an alternative method?
TIA, Nick.

it's a validation thing in the web interface, you'll need to use telnet to add those port forwards, the telnet guide is on the UK downloads page and the commands are "srv nat portmap" or "srv nat openport".

Hi again Voodle, do you know if its possible to do this with a WAN IP alais
i get <%% WAN IP addr is not in auxilary ip list> when i try using an alias

Command used is <srv nat openport add 1 1 92.43.244.160 192.168.20.5 TCP 3306 3306>
Would it have anything to do with address mapping?
Thanks,

Ok fixed this,
To use alias wan address to openport to off network address use telnet command,
ip aux add x.x.x.123 0 (x.x.x.123 being the wan alias address)
then
srv nat openport add 2 1 x.x.x.123 x.x.x.5 TCP 3306 3306 (your port)
then
srv nat openport enable 2 1 (change index numbers as openport you created)
finaly srv nat openport comment 2 name_of_your_openport
