The two connections should work as follows: the faster (PPPoE) one is the "default", every computer should use that connection unless it is down (this may be detected by pinging the gateway, or by any other means if anyone has a better idea), in which case the router should automatically switch to the slower (DHCP) connection. Internet connectivity (dual WAN with failover):įinally, I have 2 internet connections: a fast one through PPPoE and another, slower on, to which I must connect with DHCP (to obtain a public IP address from the ISP through the cable modem).Īll the networks (LAN, internal WLAN and guest WLAN) must be able to access the Internet. The guest WLAN cannot see the LAN, nor the other WLAN (the internal one).Īll the computers connected to any of these networks (LAN, internal WLAN and guest WLAN) should be able to obtain IP addresses and DNS server addresses from a DHCP server on the router. The internal one should be completely connected to the LAN (that is, all boxes on the wired network and the internal wireless network must see each other). I want to have 2 WLANs, one internal and another for guests. I want to set up one wired LAN (maybe someday I will partition this into two and connect them with another router, maybe this information could change the way to configure the WRT54G2 now, I don't know).
I have some knowledge on Linux networking and routing, but nothing too fancy. I've studied the documentation (notably, which describes the router's ports), but I can't figure out by myself how to achieve what I want. I've installed DD-WRT v24-SP2 micro on a Linksys WRT54G2 v1.0, and I'd appreciate some help on setting up a not-so-trivial network.
