Hi all,
I have a jail NAT'd to a base system, but the connection is extremely
slow and frequently disconnects drops, whereas the base is fine has
perfectly fine connectivity.
My configuration is as follows:
vtnet0: Has routeable IPv4 address and 172.16.0.1/16
Jail uses epair4b, base has epair4a. Jail's IP is 172.16.0.5/16.
The base and jail can ping each other.
bridge0: contains vtnet0 and epair4a.
I have gateway_enable="YES"
My pf.conf is as follows:
nat pass from 172.16.0.0/16 to any -> (vtnet0)
When I try to run clamav, the connectivity stalls after a few minutes
and eventually disconnects. I ran tcpdump on the bridge and saw a lot
of HTTP seq and ack packets but no actual data. I am not using IPv6
yet.
Assistance please.
Thanks
