No Winbox access

RouterOS Beginner Basics
1

Hello World !!!

I have a site with 26 Mikrotiks. The main router brings up a VPN to one of my servers to grant access
to the devices. So far, so good.
I can access all devices behind the router using winbox. The only device that is not reachable, is
the router itself.
On other sites I do not have these problems.
ROS is 6.48.5 LT
Main router replies to PING.

In short, devices 10.128.36.2-10.128.36.42 can be winboxed,
10.128.36.1 not.

Firewall rules are mainly dynamic with following additional entries:

/ipfirewall nat
add action=passthrough chain=unused-hs-chain comment=“place hotspot rules here” disabled=yes
add action=masquerade chain=srcnat comment=“defconf: masquerade” ipsec-policy=out,none out-interface-list=WAN

and

/ip firewall filter
add action=passthrough chain=unused-hs-chain comment=“place hotspot rules here” disabled=yes
add action=accept chain=input comment=“defconf: accept established,related,untracked” connection-state=established,related,untracked
add action=drop chain=input comment=“defconf: drop invalid” connection-state=invalid
add action=accept chain=input comment=“defconf: accept ICMP” protocol=icmp
add action=accept chain=input comment=“defconf: accept to local loopback (for CAPsMAN)” dst-address=127.0.0.1
add action=drop chain=input comment=“defconf: drop all not coming from LAN” in-interface-list=!LAN
add action=accept chain=forward comment=“defconf: accept in ipsec policy” ipsec-policy=in,ipsec
add action=accept chain=forward comment=“defconf: accept out ipsec policy” ipsec-policy=out,ipsec
add action=fasttrack-connection chain=forward comment=“defconf: fasttrack” connection-state=established,related
add action=accept chain=forward comment=“defconf: accept established,related, untracked” connection-state=established,related,untracked
add action=drop chain=forward comment=“defconf: drop invalid” connection-state=invalid
add action=drop chain=forward comment=“defconf: drop all from WAN not DSTNATed” connection-nat-state=!dstnat connection-state=new in-interface-list=WAN

The filters seem to be generated by the hotspot setup.

Thanks for your help.

This is most likely the issue.

add action=drop chain=input comment="defconf: drop all not coming from LAN" in-interface-list=!LAN

You need to add your vpn to the LAN interface list or add an accept rule above it for for vpn.

Thanks a lot 2frogs,

for now I have disabled the firewall rule you mentioned.
Was sure I already tried, but it has been a long day…

You shouldn’t disable that rule, when disabled it allows access from internet. You should add the vpn to LAN list or add an accept rule for the vpn.
