Hello. We are facing some problems trying to manage good L2 connectivity across WAN link. From one side we have CCR1009, from another x86 mikrotik kvm based VM. Fw version 6.42.12. We set up EOIP + IPsec. Both ends has static ip address, connection speed is 1Gbit/sec, latency 60ms. I know this is really bad for such network desing, but it is very bad for now. Services that relies on TCP, demonstrate very poor performance, SMB file copy - 20-30Mbit/sec, rsync, nfs, scp about the same. I know about tcp window size, and many people dealing with high latency links this way, but iperf -w does not help and shows the same result, as i mentioned above. I thought it can be MTU issue, but settings are pretty common, 1500 on lan-bridge and auto MTU on EOIP interface (1308 calculated by PMTUD). So, any help would be appreciated
