I have a FreeBSD 4.9 box with three network interfaces setup as follows: fxp0 - 172.16.20.2 fxp1 - 192.168.1.2 bge0 - promiscuous mode, no-arp
fxp0 is connected to a netgear switch, fxp1 is connected to a Cisco 2900xl and bge0 is also connected to the Cisco but is listening on a span port to everything transmitted on the 192.168.1.0/24 subnet. Here's the weirdness, when sending an ICMP Echo request to fxp1 from the switch at 192.168.1.254 duplicate replies are seen coming back. The same thing happens when sending the same requests from fxp1 to any other address on the subnet. When the bge0 interface is brought down the issue goes away and everything is normal. systat shows the requests going out and the same number of replies coming back in. ipfw is being used to deny all icmp via bge0. I have Googled extensively for this issue to no avail, so, anyone have any ideas? -------------- Nigel Houghton "I have read of a place where humans do battle in a ring of Jell-O." _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
