Port forwarding problem

[maxxer]

I've weird networking problems in a virtualized pfsense.
LAN is 192.168.1.0/24

I configured two port forwards, one to 192.168.1.47 (physical KVM host) and one to 192.168.1.49 (another physical host in the lan).
If I try to ssh to the port of .49 everything works, while against .47 it does not!
I also have a VPN here, I can ping .47 & .49 fine, but I can only ssh to .49, 47 will timeout.

I managed to catch a tcpdump while trying to ssh to .47 (via portfw):

tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on vtnet0, link-type EN10MB (Ethernet), capture size 96 bytes

it seems it's replying to me, but the connection never gets established.
firewall > nat > outbount is set to automatic.

What could be the cause?
What makes work for .49 and not for .47?

thanks

is the gateway filled in correctly on the KVM box ?

yes, in fact ping works fine…
