VPN Tunnel Interface Support for IP Helper
The VPN Tunnel Interface can support IP Helper. DHCP Replay in IP Helper with Tunnel Interface Support shows a simple example of DHCP replay in IP Helper:
- PC is the device needed to get an IPv4 address from the DHCP protocol.
- GatewayA is the gateway-enabled IP helper.
- GatewayB is the gateway with a DHCP server.
DHCP Replay in IP Helper with Tunnel Interface Support
To configure IP Helper with a VPN Tunnel Interface
The numbers in DHCP Replay in IP Helper with Tunnel Interface support correspond to the numbered tasks.
- In PC:
- Connect to the LAN (X0) subnet of GatewayA.
- Set to obtain an IP address through DHCP mode.
- Set up a VPN tunnel between GatewayA and GatewayB.
- Add a VPN Tunnel Interface.
- In Gateway B:
- Add a route entry from the Tunnel Interface’s IP address to GatewayA’s X0 interface.
- Add the outbound interface of the Tunnel Interface.
- Add an IP address range as the DHCP scope for PC.
- In Gateway A:
- Enable IP Helper.
- Add an IP Helper DHCP relay protocol from X0 to GatewayB’s Tunnel Interface address. The protocol is DHCP.
