Re: [gentoo-user] ATT DSL + Westell modem/router = Gentoo woes
I am not familiar with the modem in question, but if you are using your own router the modem should be set up in fully bridged mode and the PPPoE authentication will be managed by your Gentoo router. Thanks Mick. The Westell does have an option to take PPPoE off of the device and I'd like to set that up soon. Right, without the PPPoE disabled the modem operates in a half-bridged mode (essentially it is a router running dhcp and 1:1 NAT). I would disable NAT, dhcp and PPPoE on the modem so that it is in fully-bridged mode and then see if the problem is resolved. Your symptoms are typical of a half-bridged router and a dynamic IP address from the ISP. Usually, the client on the LAN does not know when the ISP's WAN side IP address has changed and will not pick up the new address until the dhcp lease on the client has expired. To overcome this botched implementation the half-bridged modem has a short lease. This doesn't always work, as I suspect is the case here. HTH. -- Regards, Mick Thank you Mick, I'm going to set that up ASAP. - Grant

Re: [gentoo-user] ATT DSL + Westell modem/router = Gentoo woes
I recently switched from cable to DSL on a Gentoo router and I'm having trouble keeping a stable connection. Periodically I need to run '/etc/init.d/net.eth0 restart' before it will connect to the Westell modem (which is also a router although ATT won't admit it). The weird thing is that rebooting the system doesn't reacquire the connection. I have to actually issue '/etc/init.d/net.eth0 restart'. Does anyone know why rebooting doesn't reacquire the connection and restarting the interface does? - Grant I just use the modem to login and then enable ip pass thru to my router which is a linksys running DD-WRT; http://www.dslreports.com/faq/7073 This set-up has worked well for a few years without me having to do anything. Could I get you to tell me a couple of your settings? You're doing something right if you haven't had to touch your's after setting it up. I'm trying to figure out the right connection type (or something like that) for which the options are something like Smart KeepAlive, Always Reconnect, and Connect On Demand. The other one is the IP lease timeout. It defaults to 10 minutes and I just set it to 99 days, but I don't want it to expire even after 99 days. I have a static IP but I think this is the timeout between the modem/router and the Gentoo router. I am not familiar with the modem in question, but if you are using your own router the modem should be set up in fully bridged mode and the PPPoE authentication will be managed by your Gentoo router. Your Gentoo router will also use dhcpcd (or similar) to obtain an IP address from your ISP after it authenticates on their RADIUS server. In a nut-shell: You want to set up your modem to not do NAT, or dhcp, or authentication at all, but transparently encapsulate your PPP into ATM packets and send them off to your local DSLAM. All the communication with your ISP will be managed by the router and your router will have the static IP address given to you by your ISP. The modem will only have a LAN address which you will need to set up manually on it, using its control panel. PS.

Any idea why that would happen? - Grant

I have a niece that has the one you are talking about and she has to reset her stuff pretty regular. She is not computer inclined so she just turns everything off, waits a bit then turns everything back on, modem first of course. Could it be that that modem just has some issues for some reason? My niece runs windoze on her puters, she has two. I wouldn't think it was OS since the only common thing is that modem. Just a thought. Dale :-) :-) P. S. Don't expect ATT to admit anything. They told me their DSL would even work with Linux at all.
