Hello all,
I was having issues connecting with ssh/https/etc to my mikrotik hex router after I updated it to 6.45.3.
I have solved the issue and it is working, but I have zero idea why it works. I'm just trying to learn a little.
I'll post config snippets at the bottom, but a general idea of the way I have it set up is..
bridge1: # 192.168.88.1/24
- eth1 # WLAN
- eth2 # desktop. has 192.168.88 address from dhcp
- eth3 # access point. not important
--
and then I have a interface list named "LAN" with "bridge1" in it.
The reason I couldn't ssh was this firewall filter
6 ;;; defconf: drop all not coming from LAN
chain=input action=drop in-interface-list=!LAN log=no log-prefix=""
Which I assumed would not affect connections from my desktop -- since my desktop is coming from bridge1 which is in the LAN list.
When I added this rule above it..
5 chain=input action=accept protocol=tcp in-interface=bridge1 dst-port=""
log=no log-prefix=""
everything worked fine. If the rule was added below it -- ssh would not work.
Why would the firewall rule that uses in-interface-list not work the exact same as a rule except it specified the interface directly? In my head the rules are basically identical.
heres the /export with the rule that fixed it. If the

Any knowledge is very much appreciated. Been a fun day messing with this! This community seems pretty great.
