Hi List,
When using ipnat, part of ipfilter 4.1.13, I don't see any
icmp packets being returned saying:
Host Unreachable, frag needed and DF set.
type 3, code 4
It does work if I am not using ipnat.
Any ideas?
Thanks,
Steve
Sorry for the noise - this seems to be OK. But the problem I am seeing
relates to:
Did something change in 6.2? If my mtu size on rl0 is 1280 it won't
accept a larger incoming packet.
kernel: rl0: discard oversize frame (ether type 800 flags 3 len 1514 > max
1294)
I don't think it worked this way in the past.
Won't this affect pmtud?
man page for ifconfig says mtu limits size of "transmission" not reception.
"mtu n Set the maximum transmission unit of the interface to n,
default
is interface specific."
