Hello,

I am running in= to a strange network issue with jails on one host and cannot figure out wha= t I did wrong=2E

I have two jails:
- 104 is a shared IP jail (cla= ssic) with an alias on the host's em0
- 115 is a vnet jail with interfac= e vnet0=2E192

There is a bridge0 bridge with em0 and vnet0=2E192 as = members

I cannot have the two jails talk together=2E
More precise= ly, 115 -> 104 works, but not 104 -> 115=2E
I did tests with netca= t and tcpdump on the host's bridge0=2E
I can see SYN packets from 104 ge= tting sent repeatedly but no response=2E
If I initiate from 115, I canno= t see the initiation packet (??) but I can see the SYN+ACK coming in repeat= edly from 104 too=2E

Any idea what's wrong and how to fix it?
Kind regards,
DaLynX
