i have a strange problem on multiple routers.
it seems if i do a portscan of any hosts thru the MT router.
it always says port TCP 1720 is open.
even if i make a block all rule.
all the other ports are closed, but again TCP 1720 is open.
i know its used by the old telephonie package, but i don’t have this package installed.
any idea’s???
which packages you have enabled??,

Check your destination nat rules. You can post them here with:
/ip firewall nat print dstnat
uninstall telephony package. also you can try to disable the H.323 service port in “/ip firewall services”
did that already. i disabled the H323 and SIP in services
packages installed
advanced tools
dhcp
hotspot
ppp
routerboard
routing
security
system
wireless
no disabled packages.
