Hello and good day!
I'm testing and comparing features between SkyNet and pfSense firewalls. After favorable testing and marking notes, I've uninstalled SkyNet ... are there residentual files I should clear? Should I flush iptables?

During the SkyNet testing, I configured WireGuard VPN access directly to ASUS ... shoud I disable or delete this configuration?

After bringing pfSense online for testing/notes, ASUS LAN (x.x.51.x) clients have Internet access via ASUS WAN (x.x.50.5) gateway, pfSense LAN (x.x.50.1), and pfSense WAN (68.x.x.x). I'm having a problem with WireGuard VPN access to ASUS LAN via pfSense ... VPN access works for pfSense but not ASUS; previously worked for both.

pfSense shows ASUS WAN gateway offlineand pings to ASUS WAN and ASUS LAN are not returned ... should I activate ping (1st step in troubleshooting?) via the ASUS GUI and add ASUS iptable settings:

Code:
iptables -A INPUT -s 68.x.x.x -p ICMP --icmp-type 8 -j ACCEPT # Specific pfSense WAN address
iptables -A INPUT -s x.x.50.1 -p ICMP --icmp-type 8 -j ACCEPT # Specific pfSense LAN address
iptables -A INPUT -s x.x.51.1 -p ICMP --icmp-type 8 -j ACCEPT # Specific ASUS LAN address
iptables -A INPUT -p ICMP --icmp-type 8 -j DROP # Drop other external and internal ping attemps

Am I missing anything to re-enable VPN access to ASUS LAN? In advance, thanks for your expertise, consideration, and guidance!

Thanks. Danny.

Skynet is an IP-blocker script. pfBlocker NG package does this in pfSense. Not a firewall.
Recieved and clarification appreciated!
