Hi,
I tried on FreeBSD 10 and FreeBSD 11
Linux 2.6.8 --> ipfilter/FreeBSD 4.10 -> FreeBSD 5.4
ssh from Linux to FreeBSD 5.4 with rule on the ipfilter/FreeBSD 4.10 box
in the middle.
pass in quick on lnc0 proto tcp from 10.1.0.0/16 to 172.31.0.0/16 port =
22 flags S keep-state
The Linux box is on the 10.1.0.0 and FreeBSD 5.4 on the 172.31.0.0.
Once the Linux sets the TCP window scale to 7 (TCP option 3), the ssh
will stall and then reset under some load. The SSH login and a few "ls"
command worked fine.
Any help is appreciated.
