Hi Michael, You are not missing anything, there is no selective "Deny EXT->Local" as that is the default.
Two solutions come to mind ... 1) Recreate the "Pass EXT->Local" to multiple entries to not include what you don't want to allow. 2) Add a custom rule in /mnt/kd/arno-iptables-firewall/custom-rules to implement the desired "Deny EXT->Local". -- untested example custom-rules -- deny_ext_local() { local proto="$1" host="$2" port="$3" echo "[CUSTOM RULE] Deny EXT->Local for Proto: $proto, Host: $host, Port: $port" iptables -A EXT_INPUT_CHAIN -s $host -p $proto --dport $port -j POST_INPUT_DROP_CHAIN } deny_ext_local udp 1.2.3.4 5060 deny_ext_local tcp 1.2.3.0/24 5061 -- (and test) Lonnie > On Aug 16, 2021, at 8:02 PM, Michael Knill > <michael.kn...@ipcsolutions.com.au> wrote: > > Yes. > > Regards > Michael Knill > > On 17/8/21, 10:35 am, "Lonnie Abelbeck" <li...@lonnie.abelbeck.com> wrote: > > Are you saying you added a "Pass EXT->Local" but now want to deny a subset > of that ? > > Lonnie > > > >> On Aug 16, 2021, at 6:20 PM, Michael Knill >> <michael.kn...@ipcsolutions.com.au> wrote: >> >> Hi Group >> >> Forgive my ignorance but just wondering how I do this.
