Subject: [LARTC] Multiple ISP Links - Gateway Not Getting Restored
Date: Sat, 31 Dec 2005 14:59:37 +0000	[thread overview]
Message-ID: <43B69A09.3030205@tuxspace.com> (raw)

I have been successfully implementing load balancing gateways for 
multiple ISP links at various locations using Julian's patches and as 
suggested in LARTC HowTo. At one location, one of the ISPs is providing 
connectivity through a PPOE DSL link which has to be dialled in 
everytime to connect. The gateway has been configured on a Fedora Core 3 
based system and I have recompiled the 2.6.12 kernel after applying 
Julian's patches. I have configured the DSL modem in bridge mode and 
connected it to an ethernet interface on the gateway and use the DSL 
dialer in Fedora Core 3 to connect to the ISP. This creates a ppp0 
interface when the connection goes live which is alloted a static Public 
IP. The dialer has been configured to redial as and when the link goes 
down. However the problem is that the kernel is not able to detect when 
this DSL interface (ppp0) comes back and does not restore the gateway 
through this link. The loadbalancing script has to be run again to make 
the kernel treat this gateway as LIVE and make the traffic go out 
through it.

Has anyone encountered a similar problem ? I have never come across such 
an issue wherever the link is terminating on an ethernet interface. This 
ISP is insisting on dialling and then establishing the a PPOE interface. 
Any suggestions ?

Thanks,

Manish
