Problems with NAT rules stop working v3.25

I have had this problem on multiple routers now, the most recent happening twice a day.

Hotspot login screen stops working, login screen hosted on remote server and walled garden setup for it. Local login page on mikrotik redirects to remote.

When this happens a deletion of the masqurade statement and re-creation of it fixes the issue. A factory reset and reconfig fixes everytime as well.

I have also had the same issue with not hotspot setups, same fix applies.

Any ideas? a bug?

Thanks,

at first, try to upgrade to 3.27

what kind of routers do you use?

x86 systems.

hm… where do you use masquerading?..

Here are the NAT rules:

ip firewall nat pri

0 X ;;; place hotspot rules here
chain=unused-hs-chain action=passthrough

1 chain=srcnat action=masquerade src-address=10.123.4.0/22

2 chain=srcnat action=masquerade src-address=10.123.0.0/22

and didn’t upgrade to 3.27 solve the problem?

Did not.

sorry, I’m not familiar with Hotspot, I don’t use it… NAT is working fine for me in v3.x…
