2 WAN's to one router, is it possible?

Sparky

Basically i have a WRT54g and am using a cable modem to connect into the internet port of the router, all i want to know is it possible to say connect a dsl modem into one of the lan ports to enable net connections to the other computers on the lan and wireless network.

Only reason i ask is in case's where the cable connection fails there is atleast a dsl connection there.

If it helps i already have a linksys adsl gateway router, could that be bridged to the wrt54g?

Cheers lads

http://www.hotbrick.com/produto.asp?tipo=2&codPro=22 with its two WAN ports is probably what you're looking for.

Quck hack: but you could set the local machines to use the Linksys as the default gateway first, and then give them a batch file to change the gateway to the DSL router if there's an issue.

route add -p 0.0.0.0 mask 0.0.0.0 dsl.router.ip.here

Linksys does a cheap load-balance/fail-over router, the name escapes me. It hasn't gotten very good reviews, though.

Use a server instead of the linksys. Thats what i did for a similar setu man

mmmm, sounds good, that just might jump that plan of a whole house network storage server in to my head again.
Id assume 2 NIC's (wans) and the 1 for the router will be needed, and software? any suggestions on software, and load balancing?

That would be enough to make me stay away

Wingate proxy SW would let you even automatically use one WAN for WWW and another for FTP.

Disable NAT and setup a "proxy server" for each king of thing / port.

YOU MUST "bind" each in connection of a proxy service to the LAN NIC and then it is 100% secure if WWW based log server interface disabled. In older versions of Wingate this was not a default and inexpert users thus created an "open" proxy. All versions Wingate have always been 100% secure IF the web interface and remote control is disabled and all ports bound / mapped to correct NICs.

Install NO sw on the Workstation PCs.

You will need "Filezilla" FTP client for FTP sites that don't work via Netscape/Opera/Mozilla/Firefox/IE webbrowser. Filezilla can be setup to use the Wingate FTP server proxy. Filezilla is best Windows FTP client I have see ever.

I using an old version on a P90 64M RAM NT4.0 box with 2 NICs.

Disable MS binding for EVERYTHING other than TCP/IP and the LAN ports are secure in Win98/NT4.0/Win2000/WinXP.

Disable all MS servers (Telnet, HTTPS, Personal or IIS web, Server, Browser etc).

DON'T use this box as a house server!

Similar setup and security precautions for Linux. A new Distro would need 128M RAM and P600MHz at least. RH6.0 or NT4.0 are a better solution for a firewall using up an old PC. My firewall running NT4.0 uses 22M RAM!

I also have a dynamic DNS updater for the service provided by www.dyndns.com. Only needed if you have a public INWARD proxy, ideally mapped to a particular PC (say a particular Game for Internet play or a hardened web server or specialist application like APRS or DX Cluster.)

I have a dialup modem for backup and it can be used by the proxy. My mail server and PCs see no change other than incomming speed goes from 3000k to 40k!

Yup 2nics for each of your WANS and one nic for your network(Out into a gigabit switch) In my setup the machine is also a fileserver mailserver webserver streming mediaserver and domain controller.
Windows server 2003 standard has it all built in as standard.

Yeah that would work but is very complicated in comparison to y solution

That's bananas. I'm running a firewall using Slackware 10 on a PII 266 with 64MB RAM and that's overkill. Do you think someone's going to run an X server on a firewall?

I'd imagine one of the firewall distros (Smoothwall, ClarkConnect, IPCop, etc) would probably support this kind of fail-over and/or load-balancing.

masteroftherealm

Yup most Linix distros support HSRP and IP Load Balancing.
