How do I VPN only 1 host device?

seitys

It doesn't work for me. Here are my firewall rules in order from top to bottom.

Protocol: IPv4, Source: Desktop (alias for 192.168.1.2, Destination: blank, Gateway: VPN
Protocol: IPv4, Source: LAN net, Destination: blank, Gateway: DHCP WAN
Protocol: IPv4, Source: blank, Destination: blank, Gateway: default
Protocol: IPv6, Source: blank, Destination: blank, Gateway: default ipv6

Rules 3 and 4 are there by default but I left them as is because the firewall reads the rules from top to bottom so rules 1 and 2 should take care of traffic for the entire LAN net.

Yet, when I turn on VPN, every since device on my network passes through the vpn, not just my desktop.

Using manual outbound NAT?

seitys

Yes manual outbound NAT although I haven't added any additional outbound NAT rules.

Currently I have 4 outbound NAT rules.

Interface: WAN, Source:L 127.0.0.0/8, Destination: blank, Destination Port: 500, NAT Address: (my ISP WAN address here), NAT Port: Blank, Static Port: Yes
Interface: WAN, Source: 127.0.0.0/8, Destination: blank, Destination Port: blank, NAT Address: (my ISP WAN address here), NAT Port: Blank, Static Port: No
Interface: WAN, Source: 192.168.1.1/24, Destination: blank, Destination Port: 500, NAT Address: (my ISP WAN address here), NAT Port: Blank, Static Port: Yes
Interface: WAN, Source: 192.168.1.1/24, Destination: blank, Destination Port: blank, NAT Address: (my ISP WAN address here), NAT Port: Blank, Static Port: No

These are the 4 default settings.

Edit: partially deleted because I wasn't being accurate. I've staring at this too long, all day, and its making me delirious.

The one you had before…

Interface: OpenVPN, Source: Desktop (my alias for 192,168.1.1), Destination:blank, Destination Port: Blank, NAT Address: (my VPN address here), NAT Port: (VPN port), Static Port: Yes

Remake that one and put it at the top of the list.

BTW - If 192.168.1.1 is your desktop IP, then what is the LAN IP of pfsense?

Did you mean to type 192.168.1.2 as IP of desktop?

seitys

Yeah ignore what I wrote for that because the source for NAT outbound only has "any," "This Firewall (self)," and "Network" so I wasn't sure what to put there. If I put 192.168.1.0 then my entire subnet would be redirected to the VPN which is not what I want. I thought of creating a separate subnet but I was hoping I didn't have to because I think that could get messy when changing configurations.

Edit: I'm going to try

Interface: OpenVPN, Source: any, Translation: Desktop () and leaving everything else blank.

Edit 2: Okay but I just thought about it. Even if I added that outbound NAT rule, it wouldn't fix anything because it translates everything from my VPN to my 1 host and then it should go down the list, where it should translate everything else to my ISP WAN IP but it doesn't do that.

kejianshi

No - you need to have the ip of the desktop in there with a /32 behind it. And it needs to be top of list.

Interface: VPN, Source: 192.168.1.2/32, Destination: blank, Destination Port: blank

seitys

Why 32? My entire subnet range is only 192.168.1.1 to 192.168.1.254.

kejianshi

OK - here is the thing.

There is actually no need to create firewall rules actually if you are using manual outbound NAT.

You can just do it on manual outbound NAT.

Seems like you have mixed together a couple of how-to docs…

The reason you enter a /32 behind the desktop IP is because a /32 is one IP where as a /24 is 255. 256 if you count 0.

seitys

Interface: VPN, Source: 192.168.1.2/32, Destination: blank, Destination Port: blank, NAT Address: (my VPN address) NAT Port: blank

I just added that rule and my entire network still defaults to the VPN instead of just my desktop.

Can you post a pic of your outbound NAT and a pic of your LAN firewall rule?

How do you post images? I'm a newb at forum stuff.

kejianshi

may I see you alias for desktop also please?

In your outbound NAT, what is that 207 address? Why doesn't that just say WAN?

seitys

its my WAN IP. It says the actual IP instead of WAN because that is the default setting. If I were to remove it and add it again, it would show up as WAN, not the actual IP in numerical form. The only 3 choices in the translation section are interface IP, host alias and other subnet.

kejianshi

I'd make it WAN.

Then I would delete those first two firewall rules you added on the LAN where you modified the gateway.

Then try it.

seitys

Still the same result.

Why are the firewall rules and NAT outbound rules redundant?

From my understanding:

NAT rules translates my internal IP to an externally registered IP.

Firewall rules dictate what traffic can be allowed into my network.

Aren't those 2 different functions?

kejianshi

perhaps this is a 2.2 weirdness.

seitys

okay here is something.

Before, every how-to guide mentioned the VPN as another gateway but with the settings in how-to stickied above, the gateway was always offline. BUT, if I remove "redirect-gateway def1" from the advanced setting when configuring vpn, the gateway now shows as online.

Now that I've done that, the opposite thing happens. Only some of the traffic is going through the VPN but my desktop IP is not showing the VPN IP. And I'm not sure what traffic is going through the VPN but its much less than before.

Are you opposed to posting your vpn config?
