Hello
I have 2 networks, which are connected over a VPN. In the network A,
there is a DHCP server.
In network B I have the client. But all client address from source
192.168.3.x get a IP from network 172.18.1.x with NAT and then the
traffic goes through the VPN tunnel.
On the router in network B I have an ip helper-address to the DHCP
server.
Now the server gets the Discover from the client with the following
informations:
Source IP 172.168.1.1
Destination: Address from DHCP server
Relay Agent IP Address: 192.168.3.1
The DHCP server will now send back the offer. But the servers sends it
to 192.168.3.1 and not to the address 172.168.1.1
How can I change that?
Yours sincerely
