Why doesn't IDLE Timeout work in RouterOS?

Question

VPN

Colleagues, please tell me:

RouterOS has an IDLE Timeout parameter in the PPP profile properties, the problem is that the inactivity time is constantly reset by protocols like WSD and UPNP that crap in the tunnel.
Is it possible to somehow configure RouterOS so that it does not consider this traffic a condition for resetting the inactivity time?

Answer 1

:local a 0
/ip fi ma add chain=prerouting action=accept src-address=$"remote-address" protocol=tcp dst-port=3389,445 comment=$"user"
while ($a!=60) do ={
:local j [ip fi ma get [find comment=$user] packets]
:delay 10
:local k [ip fi ma get [find comment=$user] packets]
if ($j=$k) do {: set a (a+1)}
if ($j!=$k) do {:set a 0}
}
/ppp secrets disable [find name=$user]
/ppp active remove [find name=$user]
:delay 20
/ppp secrets enable [find name=$user]

Answer 2

Try filtering on the preroute, on the raw tab for the necessary ports, if that doesn't work, I have an idea only a firewall or disabling the default route in the connection settings
