Hello,

I really don't have idea how to do but I am sur it's possible.

I have my router on OPNsense connected via wireguard VPN to 2 servers.
both are in the same ip range: 192.168.1.0/24
Today with route and gateway I can access on one subnet without problem.

I would like if I want ping the device 192.168.1.123 on gw1 I use this address 192.168.2.123 and for the same device on gw2 192.168.3.123.
my subnet is 10.3.x.x/24

Any idea?

Hi,

On my router I have some interfaces:
The WAN
The WG-OZ it's VPN tunnel connected with another OPNSENSE in another country with his own remote LAN 10.2.1.x

The LAN 10.3.1.x
The PVE 10.3.2.x

I have a static route to use the GW with VPN for the subnet 10.2.1.0/24.

From LAN I have access to internet, the LAN subnet 10.3.1.x, the PVE subnet 10.3.2.x and remote LAN 10.2.1.x
From PVE I have access to internet, his own subnet 10.3.2.x and that's all.

My problem is I would like LAN and PVE have the same behaviour. From PVE access to remote LAN 10.2.1.x.

Any idea?

General Discussion / SIP protocol thru 2nd gateway
April 14, 2025, 04:17:54 PM
Hi,

I have SIP phone on OVH with the sbc6.fr.sip.ovh domain. But where I actually live I cannot access to this domain.
Until now I use SIP phone connected to my router with redirection to another router in France via wireguard and everything was ok.
But this phone die and I would like to use softphone without redirect full ip flow but just the SIP.

If I use openvpn to connect to the router in France, I get my connection.

How should I do?

For apt update same probleme.



My architecture:

PVE with OPNsense VM.

This computer, phone etc are connected in DHCP via Vmbr0 without problem.


I don't know if it's PVE or OPNsensewith bad settings.

General Discussion / multi-wan with one via wireguard
November 07, 2024, 05:41:58 AM
Re,

Here my network https://ibb.co/nbqbfvd

The connection between the two firewall is made by wireguard with this tuto
https://docs.opnsense.org/manual/how-tos/wireguard-s2s.html

PCs are connected on local internet without problems and access to the server via static route.
What I would like is the PC3 is connected to remote internet.
I try with this tuto but without success https://docs.opnsense.org/manual/how-tos/wireguard-selective-routing.html

I am sure I miss something or I don't understand the concept.

Voilà, voila

Virtual private networks / VPN in VPN
November 04, 2024, 06:34:12 PM
Hi,

We don't know why but I cannot connect at work with their VPN when I am in Azerbaijan. It's work when I am in France.
I have also personnal wireguard tunnel to my home server in France and I can connect without problem. I have declared 2 gateways and one static route to access remote LAN from oversea.
I would like to route the VPN traffic (or all but just this pc) to the wg gateway.

I really don't understand where to start.

Bonjour,

Sur mon routeur tp link je mets Dynamic IP et ca fonctionne. je n'arrive pas à trouver l'équivalence sur OPNsense, j'ai essayé dhcp sans résultat.

Une idée ?
