Good day!
i have RB3011UiAS with latest update i am having issue i can't open many websites
mostly "https" even www.mikrotik.com i cant open & ip cloud service also not updating
please help thanks.
This is an indication that your router is misconfiguredi set DNS rule because without that i can't even use google.com.
Working fine might not be that safe security wise.i am not having any firewall previous router was working fine i just installed MT yesterday with same subnet.

pervious router mtu 1480 & mikrotik running on same mtu i have tried 1492, 1500, 1470 but still no luck.I think MTU is the magic word (as you were looking already). Have you contacted your ISP in regards to this?
What MTU was your previous router set to?

Done but nothing changed still same after rebooted even here are the new config & yes i am using only PPPOE one ClientPaste this on terminalCode: Select all/interface detect-internet set detect-interface-list=none /ip address set [find where address="192.168.1.1/24"] interface=bridge
you have pppoe-client or dhcp client?
if you have only pppoe-client paste also this:Code: Select all/ip dhcp-client remove [find]
on nat you have 3 masquerade and the output on forum are trunked
keep the first and delete the other two

I do not see other errors, if not work, you must contact your ISP, MikroTik has nothing to do with that.
MikroTik standard "ping" packet is usually 50k (NOT the "payload", but the FULL packet), is impossible that is a MTU problem, from "ping" point of view.
Try to ping something, if work, ping with on advanced the Dont fragment flag set, starting from 1500 and subtract 2 until work.
When work, that value is probably your max MTU.

Solved champion my ip is dynamic from ISP tried to reboot but still getting same ip so finally when i got new ip all system starts working fine.Possibly an IP conflict, can you change the mac address on port facing ISP on the mikrotik to the previous ISP router mac address
