Hi,

I could solve the issue by my own. The "option dest lan" is missing in the 
blocking rule and the destination port must be 8443.

Hi,

I do redirect https traffic from wan to a specific ip address in lan with a 
different port:

config redirect
     option enabled '1'
     option name 'wan: Redirect HTTPS for xxxx.net:443 to my-box.yyyy.lan:8443'
     option target 'DNAT'
     option src 'wan'
     option dest 'lan'
     option proto 'tcp'
     option family 'ipv4'
     option src_dport '443'
     option dest_ip '192.168.101.92'
     option dest_port '8443'
     option reflection '1'

I would like to block some ip ranges and following the example from the 
firewall documentation.

config ipset
     option enabled '1'
     option name 'dropcidr'
     option match 'src_net'
     option loadfile '/var/dropcidr.txt'

config rule
     option enabled '1'
     option src 'wan'
     option proto 'tcp'
     option ipset 'dropcidr'
     option dest_port '443'
     option target 'DROP'
     option name 'DROP-HTTPS-WAN-LAN'

It doesn't block redirected traffic from wan at 443 to the internal lan at 
8443. I did try it with port 8443 in the blocking rule too, but it doesn't 
block anything. How must I define such a blocking rule?

With firewall3 (iptables), I did add the the following to firewall.user:

ipset restore -file /tmp/https_blacklist.conf

iptables -n --list https_scan >/dev/null 2>&1
[ $? -eq 0 ] && iptables -X https_scan
iptables -N https_scan

iptables -A https_scan -m recent --name HTTPS_BLOCK --rsource --update 
--seconds 1800 --reap -j DROP
iptables -A https_scan -m recent --name HTTPS_BLOCK --rsource --set -j LOG --log-level 
info --log-prefix "HTTPS blocked: "
iptables -A https_scan -j DROP

iptables -A forwarding_wan_rule -p tcp --dport 8443 -m conntrack --ctstate DNAT 
-m set --match-set HTTPS_BLACKLIST src -j https_scan


How can I define a similar rule set for firewall4 (nftables)?

Hartmut
