Eoip over 2x adsl bonding speed

RouterOS General
1

Hi Guys,

I have a problem with EOIP over ADSL Bonding.

I have equipment in a data center running mikrotik OS. With one public IP with a 100mbit connection.

In the remote area I have 2X ADSL2+ connections.

I have successfully bonded the connections form the remote location using 2x EOIP tunnel, One on each ADSL tail.
When I conduct a speed test from the remote router to the data centre router I get approximately double the speed (15mbps) of a normal ADSL connection (8mbps) , but when I use speed test form behind a masqueraded connection the speed is 600kbps. I think I might have something to do with the MTU.

Any help would be appreciated

Thanks Again
Paul

Use ovpn tunnels instead of eoip tunnels, ovpn keeps the mtu t0 1500

Thank you for your advise, but when i dial the internet through 2x pppoe connections the mtu is set to 1480. Am i right in saying a vpn with a mtu of 1500 will not work correctly due to the overheads in the pppoe connections?

what bonding mode do you use? bonding-rr is not recommended on high-latency links because of OOO packets

I used xor

Hi,

I believe you could check if it’s and MTU issue lowering the MSS at /ip firewall mangle:

add chain=forward protocol=tcp tcp-flags=syn action=change-mss new-mss=1400
