Hi all, Last monday, one of my colleagues got to me and said he couldn't reach several webpages. I looked into it. We weren't able to make network connections to several websites. Later on, even mail exchange with several hosts wasn't possible.
It now turned out that network connections are made, but die after the initial request. This is true for HTTP and SMTP to several external sites. Using wireshark I see that TCP checksum mismatches do show up. On WAN-if I do have several collisions, the box is connected via a fxp to an external DSL modem/PPPoE. The ISP checked the line, no drops, ADSL is fine. So I put up a second computer, got together three xl-NICs and used pfsense-CDROM and m0n0. Both show the same errors with these websites. Strange thing now... I hooked up a laptop, and everything is just fine. I hooked up a Netgear Hw-Router and again all is great. So all in all, I have the same problems on different pfsense-based soft/hardware. Perhaps someone can try to reach www.epson.de, www.fogra.org or www.xrite.com? The setup is: 1x WAN (fxp0) PPPoE with MTU 1472 set by ISP 1x LAN (fxp1) NATed 1x DMZ (fxp2) external IPs, only forwarded from pfsense network connectivity problems do show up on LAN and DMZ. Changing the MTU doesn't seem to work as I'm then no longer able to connect to the ISP. Anyone have an idea as to what I can do next? best regards, Philon Terving --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
