So, my new RB450Gx4 went into production last night/early this morning and now Google, Google Play, and Gmail breaks…not understanding what’s happening. My IP > Settings are the same and exact as the original RB450G that the new router replaced…see the image below. Firewall is default just as the older one. The issue seems to be when Google redirects to hhtps://accounts.google.com for the login screen or when searching, https://www.google.com…It’s puzzling! Even strangely, YouTube gets through!
Try to stretch “breaks” a little, into few sentences maybe… There’s lot of ways how something can break, it would be good to understand what exactly is happening here. Try to describe it in a way that someone who doesn’t see it can understand.
Posting part of settings is not all that helpful.
/export config hide-sensitive file=yourconfigaug22
What am I doing wrong…see image below!
What I am saying is the original RB450G with the same exact routerOS with the same default firewall and the IP > Settings as shown above did not block google.com or gmail.google.com or Google play, etc.
Whereas the new RB450Gx4 with the same exact routerOS with the same default firewall and the same IP > Settings as shown above blocked those sties.
Delete the word “config”
In other words: /export hide-sensitive file=your-config-22-Aug
Or just
/export hide-sensitive
Copy/Past result here.
Last night, I switched router back to the old and was able to visit google.com as well as gmail just to confirm. Here is the result from the new RB450x4

These are the two problems I see so far:
add address=172.17.9.9/8 interface=ether2 network=172.0.0.0
add address=172.17.9.9 comment=defconf name=router.lan
Your IP addresses are both assigned to ether2 which is part of the bridge, you probably meant to assign them to bride and ether5, like your dhcp servers.
Edit: 172.0.0.0/8 is not a private ip range!!! Don’t use it on your LAN. Your configured netmask fucks up routing to any public 172.x.y.z IP.
Yes, I just fixed it to ether5; however, when I set network address of ether5 to 172.17.9.0, the router switched it back to 172.0.0.0 which is not a private network…why?
Also, I didn’t configured the netmask…the router did…ether5 is my guest network and I really only wanted a pool of eight addresses but the router wouldn’t. So, I just accepted what the router did which is 172.17.9.45-172.17.9.54.
You need to fix the mask, because it explains your problem, quite a few of Google’s networks are in 172.0.0.0/8.
Okay, I fixed it…all is well!
Oh, now wonder…thank you for sharing!
My apologies for writing the export command incorrectly.
You are in charge of the router, whip that netmask into shape!!!
