Because of hashing and the potential for different hashing algorithms going on, I don't necessarily know if I expect that; however, I would expect it to be consistent for a given flow. > ### > $snoop -d bge0 |grep ICMP > Using device bge0 (promiscuous mode) > hostname -> 192.168.234.1 ICMP Echo request (ID: 6337 Sequence number: 0) > 192.168.234.1 -> hostname ICMP Echo reply (ID: 6337 Sequence number: 0) > ### > > > So the problem only occurs on some IPs, not on all: > > ping 192.168.234.1 (gateway) works > ping 192.168.235.16 (other smartos host) works > ping 192.168.234.20 (other smartos host) doesn't work Okay, this helps. I have a working theory for what might be happening. I should have asked for this initially, but with the snoop of bge0 could you actually run snoop -d bge0 -o /path/to/some/file icmp and then after you do a few pings in the going out the bge0 case and coming in the bge1 case, could you ctrl+c and make that snoop file available please?
