hi,

i have an synology, i want it to have no access to internet
in the router you have an option "block internet access", that works great
but i still want a specific server on a port to be able to access from internet, so just port forwarded that port
but seems not to be working :)
is it possible to still have port forwarding setup AND internet block access?
 
A port forward is Internet access, so no, you can't have both - they're contradicting.
 
ok, so blacklist is also not an option then?
i have now enabled in firewall the logged packets for all types

if i go to my synology, lets say, i click on check for updates or something, so it access internet
i dont see any new packets in the logbook , how can i obtain a list of port/ip addess that is accessed by the synology ?

so i can just maybe block those remote IP's

thnx in advance
 
ow

i just entered the IP of my synology in the blacklist, now its not able to access internet, and port forwarding still working
verry good :)

but still want to know : how can i obtain a list of port/ip addess that is accessed by the synology ?
how can i see that in the logbook?
