Dear Sirs,
got a canon printer that can send max 4 scan to email then it start to trow this until reboot:
TCP 66 [TCP Out-Of-Order] [TCP Port numbers reused] 65132 → 80 [SYN] Seq=0 Win=64240 Len=0 MSS=1460 WS=256 SACK_PERM=1 80
TCP 60 [TCP Dup ACK 338#1] 80 → 58692 [ACK] Seq=1 Ack=654 Win=10867 Len=0 58692
I'm a little confused about it, but old printer of same vendor got same behavior.
Main problem is that only scan to email result in error, other way to scan i.e. from computer would not fail.
I've checked with provider, the remote connection is correctly started, then start to send data and then unexpectly end to send the file.
The printer is diretclty connected to port 6 as DHCP Client of a RouterOS 7.7 # software id = REBC-YUB1 # model = CCR1009-7G-1C-1S+.
Can you help me if this is a RouterOS config problem?
Thanks, BR
