Hi,

Thanks for replying ...

Old method in dd-wrt refer to use nvram command to separate one RJ45 Ethernet for the bridge, then create the second subnet (dhcp or not) then effectively doing iptables ...

http://www.dd-wrt.com/wiki/index.php/Switched_Ports
http://www.dd-wrt.com/wiki/index.php/VLAN_Detached_Networks_%28Separate_Netwo...

On new brand ans V24sp2 ... we can use a direct menu VLAN to detach a Lan port from bridge, create a new vlan (dhcp or not) then use it to route to two subnet.

In fact I have 2 subnets with system on each with a router an each with an Internet access, BUT I want to direct connect locally the 2 subnets by simple routing and route in each target ...

I will do (thru menu) with my WRT54GL and WNR3500L and use the manual def. with my old WRT54GS ... unfortunately it is dead and I change to a WNR3800.

Philippe.

Thnks for this "special" help ... but can you imagine, that I don't want to leave DD-WRT, even if you want to promote OpenWRT ... ????

I also read your same response on DD-WRT forum ...

Please don't help us ... any more ...

This forum don't seems to help ... only to promote ... OK ... bye.

apologize for the error ....

Philippe.

I am not promoting any certain firmware... you want port pased group switching? DD-WRT doesn't support it with Atheros based units, openwrt does... can you imagine if you want some feature that isn't supported in your current firmware that you may have to use another? You are right, i'll keep note of your nickname and ip and never will i try to help you in any post ever again.

Best Regards

Actually dd-wrt doesn't support it in a good way on the WNR3500L either. It just writes stuff to nvram, and let's the proprietary binary blob ethernet driver configure the switch. (It's the main reason I have never used my 3 WNR3500L's, I could not configure the switch)
Since the WNDR3800 has an open-source ethernet driver that doesn't configure the switch it might not work as suspected in DD-WRT.
I think buddee's advice is a good advice. If you want to stick with dd-wrt (you have a good reason to, the web interface is pretty slick), you must use a manual method.
If you have not resolved it, it's pretty simple by just adding a script that configures the switch on bootup.
Note however that the WNDR3700 and WNDR3800 and WNDRMAC have 2(!) ethernet ports. On the outside you have an ethernet port directly attached to the CPU, and a highly configurable 6 ports switch with a no-connection on the 5th port and the second ethernet port of the CPU on the 6th.
This is different from the WRT54G and the WNR3500L, which have 1 ethernet port connected to a switch.
