DSR-250N Hardware Version A2 Firmware 1.08B44_WW
Greetings. I need help regarding what should really be a fairly simple configuration. I have purchased the DSR-250N because of its multi-routed VLAN capabilities.
I have a WAN connection using DSL.
I have a public /29 subnet on my default LAN.
I have a private /24 subnet on my VLAN2.
Below is how I'm trying to route traffic.
LAN -> Routed (NO NAT) -> WAN
VLAN2 -> Routed (NAT) -> WAN
LAN -> Routed (NO NAT) -> VLAN2
VLAN2 -> Routed (NO NAT) -> LAN
I have the Routing Mode configured to Classical Routing so that no NAT is performed by default.
I have a SNAT firewall configured for VLAN2 to hide behind the WAN IF IP.
The main problem is, the VLAN2 traffic isn't getting working outbound to WAN in this configuration. If I set Routing Mode to NAT, all the traffic goes out, but my LAN is now also NAT'd and doesn't route correctly.
This is the configuration I previously used in OpenWRT on my 14 year old Linksys WRT54GS which has worked for years. Unfortunately, that router died a week ago. Seeing how the DSR-250N was advertised to do multi-VLAN routing and is a business router, I assumed it shouldn't have any issues doing a simple configuration like this.
Please help.
