Hi, fantastic, so you could try raising the MTU of interface1 to 1520 (technically it should be 1508 but set it a bit higher for now) and then set the pppoe to 1500, it will probably drop the connection, and hopefully bring it back up and run at 1500, note what you change so you can revert if needed.

Sorry the delay in coming back. I increased the max MTU on Eth1 to 1520 and PPPoE connection to 1500 but PPPoE Actual MTU still shows 1480 but not to worry.  It won't matter in after this weekend. 


One last question...I'm going to set up a VPN connection for client remote access (Windows and iPhone). There's good documentation on the Mikrotik Wiki and I plan on following the IKEv2 with RSA Authentication. Is there anything I should be aware of before setting up a VPN for remote access?

If you're going to bridge vpn clients to your LAN interface be sure to set the bridge to proxy arp.


You're going to need to allow open ports to the world - set up fail2ban firewall rules (if you hit this final input rule, add to spammer list and drop.  If you're on spammer list and you're being dropped again, add to ban list for x hours.  Block all input from ban list before reaching VPN accept rules)


Also, add these to your bogons/permabans else you'll get annoying vpn log entries:
