Main office is fiber via a local telco as well as the working remote. The remaining two offices are on Cox cable.
Remotes are routing to main office network for rdp/email/client apps/printing, etc. "Normal" internet traffic works great everywhere. I initially had an issue with traversing cox's network with pptp connections. They would build up fine and ping ok, but whenever you ran any traffic it would slow down to 1-2k. Switched them to l2tp and now I'm running 12mb down/5mb up from each of the remaining two locations. I did just notice that the bandwidth test had problems running a 'send' tcp test. Wouldn't connect for the first dozen times I tried it. In the process of troubleshooting the pptp links over Cox, the mtu and mru was dropped to 1450. Any higher and I started dropping pings and bandwidth suffered greatly. I think I've narrowed down the issue to two possibilities. 1. I have an isp that's over agressively qos my traffic. (either the fiber telco, or Cox) 2. I have a configuration issue on my equipment. I'm going to have a hard time nailing down #1 if that's the issue. #2. I'm ready to have a second set of eyes on the config and setup and let me know what's up.
