Hi All,
I have a network that sits remote and with DHCP on the central site.? DHCP
DISCOVER is reaching the server and the server is responding. DCHP? request
source IP is 10.0.8.2 which is tunnel IP which is routable IP on the network
but when DCHP responds it is responding to DHCP relay IP? (192.168.1.1) which
is not routable not reaching back, is there a way to instruct DHCP to route it
back to source IP? Or is this not a valid scenario for the DHCP relay?
Network config?
Vlan 100 (192.168.1.0/24) 192.168.1.1--WAN IP
