the network only works when I turn on the sniffer [solved]

RouterOS General

strange behavior

there is a hap ac3 router routeros 7.16.2 with ether1 on it vlan on which macvlan and then ppoe-client to the provider

mtu 1508 is installed on the ether vlan and macvlan so that on the ppoe interface it turns out 1500, main connection connects and works,

then there is an ip-tunnel with ipsec on ppoe interface also connects and work ok with mtu 1438

ping with packets of size 2000 and 5000 works fine inside the ip-tunnel

but the following problem occurs, sites do not open via ip-tunnel, but when I launch the sniffer to see what’s happening it starts working, when I turn off the sniffer it stops working again

what to do?

From the information provided, I can only guess that you have a FastTrack rule on your IPv4 firewall filter table that is incompatible with your IP tunnel.

I say that because the Packet Sniffer disables FastPath while running (thus, disables FastTrack too) and that could be the reason your IP tunnel works fine while the Packet Sniffer is running.

So, in case you have a FastTrack rule enabled, check if the problem is “solved” by disabling it.

[solved] yes I had a fasttrack rule with hw. offload
and when I turned it off, the traffic started flowing

thank you very much
