My ISP allows multiple different systems on my home network to receive different external IP-addresses. For every MAC address, you get one IP.
What I want to do is use my WRT54G to create two VLANs: one linked to one external IP and the other VLAN linked to the other external IP. In order to do this however, I must force my router to act as two different systems (so it must have two MAC addresses on the WAN port).
Is this possible? I know i could do this by adding a hub/switch and some routers, but that's just not cool (and expensive). If it is possible, is there a guide somewhere or could someone give me some pointers?
My firmware version is: DD-WRT v24-sp2 (11/02/09) std
What do you want to achieve? Two independant local networks with independant external ips? that is possible... but why that?
what you can do instead is bridge one lanport together with WAN so the connected device will get a wan ip. _________________ Router: WNDR3300 (wl0: n-Only 5Ghz, WPA2-AES, wl1: g-Only, WPA-Mixed-Mixed)

You can not assign multiple MAC addresses to an interface. You can move a LAN port into the same VLAN as the WAN port to make it switched with the modem. _________________ Read the forum announcements thoroughly! Be cautious if you're inexperienced.

Looking for bricks and spare routers to expand my collection. (not interested in G spec models)
I have a server, which I want to give an external IP which is different from the one on which i put my local network. My ISP however only allows one external IP for each MAC address. I know i can do this by adding a switch between my modem and my router/server, but that would mean i have to go buy another switch.
A VLAN solution might also work and tips in that direction are always welcome, but i would prefer two MAC addresses because that way i can keep the two IP addresses even when rebooting the server.
bridge the lan port (e.g. add it to the wan vlan) where the server is connected to the wan interface. _________________ Router: WNDR3300 (wl0: n-Only 5Ghz, WPA2-AES, wl1: g-Only, WPA-Mixed-Mixed)
