I'm wondering if I'm just doing something wrong! I have two Internet connections - one cable, one DSL. Until recently, I was just using the DSL as failover, but decided that it was a waste of bandwidth to never use it [:)] So, I started using Uplink Balancing, and I use the DSL line for things like SMTP and my Vonage connection through a Multipath Rule. Oddly Vonage works better on the DSL than the cable (probably cause my kids are on WoW or YouTube all of the time! I tried to do QoS for Vonage, but things seemed worse than better - forcing it out the DSL seems to work best.
For the most part this works fine as long as both links are up. However, the DSL has been a little flaky lately. Sometimes it shows "errors" in the dashboard, but rarely shows as "down". During these times of "errors", my outbound smtp queue just rises and rises. The only way for me to get mail to start flowing properly again is to go disable the multipath rule and/or the interface to the DSL. Then mail will start to go out the cable properly. It seems to me that because the DSL line doesn't entirely go down, the multipath rule just wins, even though the traffic flow through that interface gets worse and worse.
How can I better work this out so that email will go out the DSL primarily, but will switch to the Cable more consistently if the DSL is not keeping up with the traffic? Would QoS be a better option?
Thanks.
