Hello,
I have a weird problem with a GRE tunnel, the setup is as follows;
gre0: flags=b051<UP,POINTOPOINT,RUNNING,LINK0,LINK1,MULTICAST>
mtu
1476
tunnel inet 213.67.20.137 --> 194.145.248.113
inet 194.145.248.138 --> 194.145.248.137 netmask 0xfffffffc
And I've tried both w/ and w/o the link1 option mentioned in the man
page for gre.
netstat -rn -f inet:

when I try to ping 194.195.248.137 I have a 95% packet loss, but when
pinging from remote to 194.145.248.138 works just fine with no packet
loss.
tcpdump -eni rl1 shows this:
22:05:55.148354 0:10:a7:13:bf:58 0:10:67:0:c4:39 0800 122:
213.67.20.137 > 194.145.248.113: gre (frag 49403:[EMAIL PROTECTED])
22:05:56.158351 0:10:a7:13:bf:58 0:10:67:0:c4:39 0800 122:
213.67.20.137 > 194.145.248.113: gre (frag 49410:[EMAIL PROTECTED])
Sometimes the packet 1 or 2 packets goes through and gets a reply
though.
I use:
FreeBSD 5.2.1-RELEASE-p5 #3: Sun Apr 18 22:25:17 CEST 2004
[EMAIL PROTECTED]:/usr/obj/usr/src/sys/merltock i386
When google-ing for this problem I found this:
http://lists.freebsd.org/pipermail/freebsd-current/2004-February/02039
4.html
Which seems to be the same problem, can the bug have been brought back
afterwards?
I hope I didn't miss any info..
I will try upgrading to 5.3-RC1, seems to have been alot of fixes
since then, but I'd be glad for any information what might be the
cause of this problem.
Thanks.
Regards,
Erik
