DHCP RELAY doesn't work since VPN Implementation

Vincent HENAUX over 6 years ago

Hi Team,

I mounted a VPN with my main branch office last Friday.

VPN is correctly Mounted

Local IPs: 192.168.0.0 /22

Destination IPs: 192.168.0.0/16

Since this configuration, My DHCP relays doesn't work. If I disable the VPN connection, I works.

Relay via VPN checkbox is unchecked.

Is there something wrong in my configuration? thank you in advance

Hi Vincent,

Any reason to select those subnets? They over-rides each other, might cause a routing problem.

Thanks

Hi Sachingurung,

Just because my network admin didn't want to create all of his subnets.

Can I get around this routing issue?

At the beginning, I hope to create 2 IP ranges but apparently it's not possible in the XG.

Any ideas?

Vincent,

did you apply NAT on IPSec traffic?

I would recommend to do so.

Regards
