Hy All

I configured a traffic rules. The port is TCP 6160. This is a specified Veeam port.
When I try connect the following message repeated in debug log:
{pktdrop} packet dropped: TCP sequence/acknowledge numbers out of window (from Ethernet 2, proto:TCP, len:52, 168.xxx.xxx.xxx:1168 -> 188.xxx.xxx.xxx:6160, flags:[ SYN ], seq:1905646984/2644590838 ack:0, win:8192, tcplen:0)

./fa/3728/0/

Thanks for all reply

Firstly, an article about TCP sequence from packetlife:
http://packetlife.net/blog/2010/jun/7/understanding-tcp-sequ ence-acknowledgment-numbers/

I'd suggest to create a similar rule for TCP 6160 on top of this rule with log packet on and see if there is more information.
