RB3011UiAS IPSec very slow after loss of electricity

Hello,

Before electricity lose everything was working without problems.
After loss of electricity in data center traffic through RB3011UiAS become unusable.

We have 2 LANs connected through IPSec site-to-site, on both sides Mikrotik routers. Connection status is established, but after that there is no data transfer. For example DC replications works, but RDC or SQL connections are unusable.

I tested connections with Ipref3 through IPSec and WAN port forwarding.

The results are:

  1. WAN:
    [ ID] Interval Transfer Bandwidth
    [ 4] 0.00-1.00 sec 11.0 MBytes 92.3 Mbits/sec
    [ 4] 1.00-2.00 sec 11.1 MBytes 93.3 Mbits/sec
    …
    [ 4] 29.00-30.00 sec 11.1 MBytes 93.3 Mbits/sec

[ ID] Interval Transfer Bandwidth
[ 4] 0.00-30.00 sec 331 MBytes 92.4 Mbits/sec sender
[ 4] 0.00-30.00 sec 330 MBytes 92.4 Mbits/sec receiver

  1. IPSec
    [ 4] 0.00-1.00 sec 640 KBytes 5.24 Mbits/sec
    [ 4] 1.00-2.00 sec 0.00 Bytes 0.00 bits/sec
    …
    [ 4] 29.00-30.00 sec 0.00 Bytes 0.00 bits/sec

[ ID] Interval Transfer Bandwidth
[ 4] 0.00-30.00 sec 640 KBytes 175 Kbits/sec sender
[ 4] 0.00-30.00 sec 394 KBytes 107 Kbits/sec receiver

Could it be defect in router?

No one have faced with situation when IPSec becomes unusable slow? What could cause it and how to fix it?

Since you posted no configuration export.., my only guess would be that you didn’t exclude ipsec traffic from fasttrack.

Thanks a lot. Fasttrack it was.

It’s just don’t explain why it worked before electricity loss…
