18.1 Legacy Series / Re: DHCP relay over VPN ?
« on: April 19, 2018, 02:19:59 pm »
hello again
On my firewall logs on the Opnsense from the main site I have this :
LAN Apr 19 14:05:14 10.10.0.2:67 192.168.20.170:67 udp let out anything from firewall host itself
So, it seems that the DHCP request (port 67 ?) passes from the VPN tunnel point (10.10.0.2 is on the distant site side) to the LAN in the main site (DHCP server is on 192.168.20.170).
So, perhaps the problem is the way back.. I am not sure but is the DHCP able to give the address to the computer or phone ?
LAN DHCP 192.168.20.170 > OPNSense 192.168.20.32 > VPN 10.10.0.1 > VPN 10.10.0.2 > OPNsense LAN 192.168.69.1 > Computer
thanks
