Hello! I am an idiot. I'm pretty sure this is a PPPoE connection: it's from a 3rd party reseller, but they're just reselling good old SBC/Ameritech DSL, and screwing the customer with PPPoE. The DSL router hides the most of the PPPoE hassle (login, et. al.), but the MTU is still there...
The part I don't get is twofold: 1) Why does it work sometimes? and 2) Why does normal browsing work just fine? I've dealt with PPPoE/MTU-type problems before, and they've killed both incoming and outgoing connections. Of course, that was with another (non-Linux) firewall product. But I still don't know why it works for outgoing (NAT) stuff. Anyway, I am not physically in front of the firewall, and I don't have SSH on that box (it's against my religion to put methods to access the firewall on the firewall), I will have to change the MTU later today. Hopefully, that will fix it. Any thoughts as to why it works the way it does? Tim Massey --- John Kicklighter <[EMAIL PROTECTED]> wrote: > I agree.
