The WRT54GL enhanced firmware.

Linksys WRT54GL v1.0 and v1.1 and WRT54G v1 to v4

Linksys WRT54GS v1 to v3

Linksys WRT54GS v4







Tarifa is a replacement firmware for the Linksys WRT54GL gateway/router. It adds a list of features, solves bugs and increases range and speed. Installing is as easy as the original firmware, you can flash (and flash it back) via the web interface.

For P2P it raises the limit of maximum simultanious connections, the hash table size is set from 128 to 3079, increasing the SPI-firewall speed with at least 10%. The Linux 2.4.20 kernel is patched with CAN-2003-187, preventing Netfilter to fail to identify connections with an UNCONFIRMED status and causes large timeouts. All default tcp time-out values are set between 2 to 4 minutes.

Linksys original firmware comes with Netfilter/iptables 1.2.7., this is very old and buggy. A new UPnP gateway service came, named miniUPnP, this makes it possible to fully use the new iptables code. The new miniUPnP code is released in Tarifa b030.

The main feature of the router is the wireless interface to connect to wireless clients. Tarifa firmware increases the wireless range, by raising the transmit power. An external antenna can also be connected and selected by the firmware. For larger networks routers can be added and linked wirelessly by the WDS system.
