I am trying to recreate an existing firewall configuration created in Firewall Builder using Firewalld. It runs on a router that controls traffic in and out of our company network. The existing configuration has rules that permit traffic to be relayed out on specified ports for specified addresses on the internal network. For example: a list of addresses are allowed to get out on ports 80 and 443 for http and https traffic, any other internal machines are denied. I currently have the external interface in the external zone, and the internal interface in the public zone, with the following configuration: external (active)   target: DROP   icmp-block-inversion: no   interfaces: ens2f1   sources:   services:   ports:   protocols:   masquerade: yes   forward-ports:   source-ports:   icmp-blocks:   rich rules: public (active)   target: %%REJECT%%   icmp-block-inversion: no   interfaces: ens2f0   sources:   services:   ports:   protocols:   masquerade: no   forward-ports:   source-ports:   icmp-blocks:   rich rules: I have found examples of direct interface rules for allowing traffic out, but is there any other way (rich rule or something else I'm overlooking) to unblock traffic like the log excerpt below? As far as I can tell a rich rule with an element of service and an action of accept only allows traffic to the router, not passing through the router. kernel: [21251.995383] FWDI_public_REJECT: IN=ens2f0 OUT=ens2f1 MAC=00:1e:67:7c:95:6c:f8:16:54:37:3a:e3:08:00 SRC=192.168.10.195 DST=xx.xx.xx.xx LEN=60 TOS=0x00 PREC=0x00 TTL=63 ID=35016 DF PROTO=TCP SPT=45504 DPT=80 WINDOW=29200 RES=0x00 SYN URGP=0
