Re: linux + wan (frame relay)
We used a Sangoma Wanpipe card in a linux box for about a year and were very happy with it. We only stopped using it because we moved our office and opted for DSL in the new space. This card can also be purchased with a built-in CSU/DSU which is what we got so other than your linux box you only need to purchase this card which we paid I think $800 US for. I would recommend this card to anyone. I would imagine that most needs would be filled with this card although there are almost certainly things a cisco can do that a linux box can't.

Re: linux + wan (frame relay)
Hi! Two years ago I had the same doubt and evaluated some options. I finally decided to go for a small cisco router for the following reasons: - At that time the linux kernel didn't do traffic shaping - WAN boards were expensive and did'n have direct support in my country (Portugal) - Cisco hardware is probably more reliable than a PC with one board in it (I confirmed this since we still use Linux for the internal router and firewall all along with the cisco router for the Internet connection - PC's do fail a lot and the cisco router never failed) What we lost with this decision was: - Traffic logging and statistics - Efficient line monitoring - Free software upgrades If you are serious about this connection, spend a little bit more and buy a dedicated router or be prepared to switch PC's very fast when the the CPU hangs, the RAM fails or motherboard burns. Hope this helps!

Re: linux + wan (frame relay)
I used a WAN card (a csu/dsu) with Linux. It was a card that was not supported by the Linux kernel, so I had to obtain the driver source for the card and compile the drivers. The problem I had with that card was that I could not compile the drivers with any kernel newer than 2.0.29. The card was a RISCom n2csu/dsu and I used it successfully with frame relay. -- Andrew

Linux has drivers for the frame relay protocol, and drivers for "WAN" cards. Stock Linux kernels do not have these drivers compiled, neither in the kernel, nor as modules. One must recompile the kernel himself for WAN support. It is a fairly simple matter to add that support: merely selecting in the X or curses configuration menus, typically, for it. > That's, if I buy a wan card, can I route with Linux?

Open source = no limitation. > Can I "safely" substitute a Cisco router with a linux+wan card? It really depends on what features you need. I had a momentary reaction remembering an need of OSPF routing using Cisco equipment in a past life, but I recover knowing that OSPF has been recently added to Linux. For simple IP routing, yes, you can. For routing with filtering (firewalling), yes, you can. For routing with protocol, maybe: we'd have to look more closely.
