Title: No Internet Access for dynamic DHCP clients
Post by: webdb on March 11, 2020, 11:24:34 AM
Hi
I switched from pfSense to OPNSense and all is working fine such as OpenVPM Access from external, Port Forward to my Webserver and also my 50 ish static DHCP clients can access the internet.
But unfortunately only static DHCP clients have internet access, dynamic clients get an IP Address, default GW, DNS and they can access any device in my LAN but they have no internet access.

My setup
LAN: 192.168.1.0/24
OPNSense: 192.168.1.254

Static and dynamic clients get the same back from the DHCP Server
IP Address: either dynamic or static
DNS: 8.8.8.8 and 8.8.4.4
Default GW: 192.168.1.254
Outbound NAT is set to automatic

So again dynamic clients can ping any IP device in my LAN but not the firewall (192.168.1.254) whereas static clients can also ping the firewall

Any idea? I'm sure it's a small setting somewhere

Regards
Daniel

Did you enable static ARP? Then only DHCP clients reserved via MAC  have internet access...
