Thanks, I avoided the problem.
I can't decide which box is wrong BSD or cisco, but the MTU size of 9180
seems to have some problems.
Current configuration is following..

[Sender BSD]
ifconfig en0 inet 192.168.10.20 netmask 255.255.255.0 mtu 1500 up
route add -iface cisco64 -link en0:3.0.0.40
pvctxctl en0 64 -p 6975
route add -net 192.168.65.0 -gateway cisco64

[Cisco]
enable
conf t
interface atm 0.5 point-to-point
ip address 192.168.10.1 255.255.255.0
atm pvc 64 0 64 aal5snap 3000 3000 3000 inarp
exit
interface atm 0.6 point-to-point
ip address 192.168.65.1 255.255.255.0
atm pvc 64 0 64 aal5snap 3000 3000 3000 inarp
exit
disable

[Receiver BSD]
ifconfig en0 inet 192.168.65.72 netmask 255.255.255.0 mtu 1500 up
route add -iface cisco65 -link en0:3.0.0.41
pvctxctl en0 65 -p 6975
route add -net 192.168.10.0 -gateway cisco65
