router

I have a Linksys WRT54GL router that I don't need anymore, since I had to buy a 3G capable router (Dovado 3GN). As I only have a 3G connection at home, I want to optimize it as much as possible.

I want to setup a caching DNS server, including some blacklisting of ad domains. The router currently runs the DD-WRT firmware.

Is it possible to use this router as an ordinary computer, running only a DNS server, disabling all other features such as DHCP, WLAN, etc? Connecting it to my other router, should I simply run a cable into the WAN-port of the Linksys router?

I've tried higher values as well. Anyway, if I use the Bandwidth tab to monitor the bandwidth usage, the number of connections… >>> More
