Home Server connection problems in Networking http://www.dslreports.com/forum/r20425458 en Sat, 26 Jul 2008 23:40:52 EDT Sat, 26 Jul 2008 23:40:52 EDT Re: Home Server connection problems http://www.dslreports.com/forum/remark,20432601 efflandt : By default Linux does not like fragmented packets. PPPoE has an 8 byte header, therefore max mtu is 1492.

Try changing the Linux LAN nic of the server to mtu 1492. You can test that on the fly as root (su -) with "ifconfig eth0 mtu 1492" (or "/sbin/ifconfig eth0 mtu 1492" from a network script when eth0 comes up). That resolved an issue I had trying to send smtp to sendmail on Linux behind a PPPoE router (so it sends proper MSS for the MTU). This is an example (different eth):

You will have to hook up a switch, and the router to one port, with the server to the other.

I have a DSL connection w/ at&t that has a static IP. The services work great sometimes, while I get connection errors at other times. I can't seem to find the reason for this. I believe that it's something to do w/ my connection or my router / modem. I have had identical issues using different machines, with different OS installed. The services always work when accessed from another computer on my home network.

I have a DI604 Dlink router. The modem is the one that came w/ my subscription, a ProLine C90-610030-06.

The modem acts as a router, But I've disabled this feature and have instructed all traffic to pass through to the router. I've set up the server machine w/ a static IP (lan) and placed it into the DMZ (through the router).

Any suggestions? ]]> http://www.dslreports.com/forum/remark,20425458 Sat, 03 May 2008 11:01:33 EDT
