NAT between Celluar Interface and Ethernet Interface

Digi TransPort WR (Series)
, , , ,

Hello.

I will try to exemplify the topology.

LAN(192.168.100.0/24)–>FW<–VPN–>APN(10.0.80.0/21)<–Digi WR11–>192.168.150.0/24

I want to manage my Digi WR11 from a PC on the 192.168.100.0/24 network.

I have a VPN from a Fortinet FW to a private APN.

The Digi WR11 obtains an available IP from the private APN 10.0.80.0/21 network on its mobile interface.

The ethernet port of the Digi WR11 has the ip 192.168.150.1/24 configured.

I can ping from the workstation to the ip 10.0.80.5 that the Digi gets with its mobile interface.

C:\Users\user>ping 10.0.80.5

Haciendo ping a 10.0.80.5 con 32 bytes de datos:

Respuesta desde 10.0.80.5: bytes=32 tiempo=405ms TTL=246
Respuesta desde 10.0.80.5: bytes=32 tiempo=593ms TTL=246

Estadísticas de ping para 10.0.80.5:
Paquetes: enviados = 4, recibidos = 4, perdidos = 0
(0% perdidos),
Tiempos aproximados de ida y vuelta en milisegundos:
Mínimo = 405ms, Máximo = 1357ms, Media = 695ms

I can also ping from the Digi to the workstation.

Command: ping 192.168.100.7
Command result

Pinging Addr [192.168.100.7]

sent PING # 1
PING receipt # 1 : response time 0.24 seconds
Iface: PPP 1

OK

I need to be able to have communication from the workstation to the LAN of the Digi WR11 (192.168.150.0/24).

I’ve already tried NAT and static routes, but haven’t succeeded.

Could you support me with any suggestions please?

Hi and welcome to Digi Forum!

If you would like to reach specific devices on the WR11 LAN, you can try to use port forwarding, please see here two available options (the firewall option is more flexible so maybe would be better for your needs): https://ftp1.digi.com/support/documentation/qn_004_port_redirection.pdf

It also depends on how the LAN devices are configured, so please check that the LAN devices have default gateway/routing properly configured to use the WR as gateway.

If still this does not help, please open a Tech Support case writing an email to tech.support@digi.com, providing a backup file from the router being sure to include at least the debug,txt file in it so we can check all the details.
Please also check Digi Support levels options here: https://www.digi.com/support
