Hello Guys,
I need a helps about RouterOS DSCP tag,
I am an also ISP with a CCR1036, I am delivering LAN2LAN service over the EOIP tunnel from my core router to a Mikrotik 3011 on client-side.
One of my customers has reached me out and requesting me to stop tagging their frames with cosx48 he sent me a Wireshark capturing showing that his ICMP packets are returning with the value 48 on the IP header when he sends with cos value 0.
I told him that we do not have this kind of packet marking on my device. So I’m doing a torch look on his interface and I am seeing some packets with DSCP value 50, 48, 26, 10, 2.(see attached ) I have no idea why RouterOS is marking those packets I have checked my home routerboard and it is doing the quite same marking.
Please, how can I remove this feature from RouterOS? i don’t want my Mikrotik tagging the client’s packets.
Urgent help needed !!
