[FW1] Duplicate pings



Hi,

I experince the follwoing strange behaviour on hosts that are located behind
an interface on a firewall which is a subinterface of another.. 

It concerns interface qe0:1 behind which a /27 network is located.. When I
ping from a host I receive the following..

ping x.x.x.x    
PING x.x.x.x (x.x.x.x): 56 data bytes
64 bytes from x.x.x.x: icmp_seq=0 ttl=255 time=2.9 ms
64 bytes from x.x.x.x: icmp_seq=0 ttl=255 time=3.7 ms (DUP!)
64 bytes from x.x.x.x: icmp_seq=1 ttl=255 time=1.3 ms
64 bytes from x.x.x.x: icmp_seq=1 ttl=255 time=2.1 ms (DUP!)

64 bytes from x.x.x.x: icmp_seq=2 ttl=255 time=2.2 ms (DUP!)
64 bytes from x.x.x.x: icmp_seq=3 ttl=255 time=1.3 ms
64 bytes from x.x.x.x: icmp_seq=3 ttl=255 time=2.2 ms (DUP!)

64 bytes from x.x.x.x: icmp_seq=4 ttl=255 time=2.2 ms (DUP!)
64 bytes from x.x.x.x: icmp_seq=5 ttl=255 time=1.3 ms
64 bytes from x.x.x.x: icmp_seq=5 ttl=255 time=2.2 ms (DUP!)

I use a Solaris 7 firewall with FW 4.1 SP 2.

Has this got anything to do with the use of a subinterface??
