How to route between 2 LANs?

perfeckdark

At LAN interface access is allowed to anywhere by default. There is an appropriate rule placed in firewall > rules > LAN.
On additional interfaces you've added the allow rule must be set up manually.

I guess, your pfSense router interface is not the default gateway at the host you try to reach.

Pfsense is my default gateway

I followed this complete guide
https://airvpn.org/topic/11245-how-to-set-up-pfsense-21-for-airvpn/

I have my ISP modem in bridge mode connected to NIC 1 of PfSense
NIC2 is connected to a 10 port 1G unmanaged switch
NIC3 is connected to my Plex server PC (VPN traffic)

what firewall rules do I need to add for traffic to be passed from NIC 2 to NIC3

I see, your "ALLOW LAN OUTBOUND" rule at LAN interface directs any traffic to WAN gateway.

So add an additional allow rule for the Plex server above of this one.
Set the protocol as you need, source = LAN net, destination = Plex server

I tried what you suggested, unless I entered it wrong, it didn't work. I think the issue is plex needs to be auto discovered by the clients (xbox, ipad etc) They don't know what IP it is on the local LAN.

Are your Plex server and clients signed in to your Plex.TV account? Plex uses Plex.TV for discovery if they aren't on the same subnet.

Also the second last default IPv4 allow rule at the end of your firewall rules on the LAN interface doesn't achieve anything as the block all rule just above overrides it.

yes my clients are logged in, which is strange. At the very least my client might not see the auto discovery but should see the plex as a remote online server (this is not ideal as it will try to stream over internet, but should work at least)

for example, my iPhone connected to my home LAN NIC#2 192.168.0.0 network cannot connect to plex (when it should at least see it as a remote server, it should act like i'm not at home but it doesn't) If I disconnect the wifi and use my LTE cellular, then it connects to my plex server as a remote server

very strange, could PfSense be blocking something else here?

Do your clients connect if you manually specify the IP address of the Plex server? Have you tried disabling secure connection s on the Plex server as this can often cause issues?

@kesawi:

no they don't connect if I manually specify ip
I tried disabling secure connections but no change

what is strange is even if the clients on network 192.168.0.0 cannot auto discovery my plex server on network 192.168.123.0 , they should at least connect to plex.tv and see my server as a remote server (like when viewing from home) and they don't. So this is leading me to believe that PfSense is somehow blocking that connecting. Do I need a firewall rule to allow an outbound connection on network 192.168.0.0?

The list of ports Plex requires for access is given at https://support.plex.tv/hc/en-us/articles/201543147-What-network-ports-do-I-need-to-allow-through-my-firewall-.

Perhaps Plex needs one of these ports open to the from your AIRVPN_LAN to your LAN in order to initiate a connection?

Is there a particular reason you have the hosts which require access to the VPN on a separate LAN segment? If it is to purely contain all of their traffic to the VPN then this can be easily achieved with a few firewalls rules from your LAN network and simplify things for you.

I want my hosts to use my internet straight through my ISP (no VPN) I only want my server (which has plex, my webserver and torrents) routing through the VPN

But why can I not even ping from network to network?

From 192.168.123.20 I can ping its gateway 192.168.123.1 and I can ping the gateway of the other network 192.168.0.1 but I cannot ping 192.168.0.2 or anything else on that network, why?

How can I create a rule for example on my LAN (192.168.0.0) interface to pass any traffic with the below ports directly to my VPN_LAN interface (192.168.123.0)
UDP: 32410, 32412, 32413, 32414 (for current GDM Plex network discovery)
and then create the same rule for the opposite

kesawi

To simplify things you could put your server in the LAN subnet and create the following rules to all direct server traffic through the VPN:

Action: Pass
Interface: LAN
TCP/IP Version: IPv4
Protocol: Any
Source: Server_IP
Destination: any
Port Range: any
Gateway: AirVPN_WAN

Action: Reject
Interface: LAN
TCP/IP Version: IPv6
Protocol: Any
Source: Server_IP
Destination: Not LAN net
Port Range: any

The following two floating rules would also be required to stop server traffic from using the WAN interface if your VPN goes down (ie a VPN kill switch):

Action: Match
Interface: LAN
Direction: in
TCP/IP Version: IPv4 + IPv6
Protocol: Any
Source: Server_IP
Destination: any
Advanced Options: Mark packets matching this rule: NO_WAN_EGRESS

Action: Reject
Interface: WAN
Quick: Enabled
Direction: out
TCP/IP Version: IPv4 + IPv6
Protocol: Any
Source: Any
Destination: any
Advanced Options: Match packet on a mark: NO_WAN_EGRESS

EDIT: Corrected errors in second rule above.

If you have squid proxy running with a transparent proxy then you will need to specify the server's IP address in the Bypass Proxy for These Source IPs option. You can also add the following to the Custom ACLS (Before Auth) box in the Advanced features (this only works if you have a static IP for your VPN interface:

##Send specific source hosts via VPN
acl src_to_vpn src <server_ip>
tcp_outgoing_address <airvpnwanip> src_to_vpn</airvpnwanip></server_ip>

If you still want to keep the server in a separate subnet then create the following rule for your needs and place it before your rule which directs traffic to your VPN gateway:

Action: Pass
Interface: AIRVPN_LAN
TCP/IP Version: IPv4
Protocol: UDP
Source: 192.168.123.20
Destination: LAN Net
Port Range: 32410 - 32414

You shouldn't need a rule on your LAN as you already have one allowing all traffic from the LAN to the AIRVPN_LAN.

Finally, monitor the firewall logs on both pfSense and your server to see if traffic is getting blocked. You can also use packet capture under the diagnostics menu in pfSense to check what traffic is being sent.

thanks for the detailed instructions, I will try them when I have some time after the holidays and report back

I kept my plex server on the separate subnet (192.168.120.20 which is routing through my VPN)
I entered in the rule for the UDP ports as you described but still my plex server is unreachable
below are the packaet captures from my LAN subnet and they all show as tcp protocol not udp

When I check the AIRVPN_LAN packet capture, I see nothing from IP 192.168.0.109

my other question is, even if my LAN cannot communicate with my AIRVPn_LAN network, why can my LAN plex client not see my plex server like a remote server (like I was at my friends house etc)

kesawi

Can you please post a screenshot of your current firewall rules for your LAN and AIRVPN_LAN interfaces so that we can see the changes you've made since your original post?

Also when posting logs or masses of text output, it's better to format text as CODE (the # button above box where you enter the text for your post).

Plex clients initiate the connection to the Plex server over TCP port 32400, and this is what the packet capture shows. The LAN firewall rules your posted earlier allow any IPv4 traffic to 192.168.123.20 so this should be getting through to the Plex server. However, subsequent changes you've made could have impacted this, which is why I'd like to see your current ruleset.

For the rules you created for the Plex UDP ports, are they on the AIRVPN_LAN interface to allow traffic from the Plex server back to your LAN subnet?

A couple of things to try:

Check the firewall settings on the Plex server itself to see whether it is allowing incoming connections, particularly from the IP range of your other subnet
Run a packet capture on the AIRVPN_LAN to see what traffic is going to/from your Plex server
Run a packet capture on your Plex server to see if it is actually sending or receiving any traffic
Enabled logging on your Plex firewall rules to check if they are being triggered (you will want to enable logging, test and then disable logging to avoid flooding your system logs)

finally got it t work, I have my server on NIC#2 connected to VPN and everything else connected to NIC#1 straight to my ISP

see attached screenshots (8.png and 9.png)

last thing I noticed after getting my plex resolved is I am not able to access my webpage from the internet. I use XAMP port 8080 , and before using PfSense I had my store router set to port forward port 80 to my LAN IP 192.168.0.20 port 8080 and it worked fine.
See screenshot (10.png) I have firewall rule for WAN to forward and destination port 80 (http) packets to AIRVPN_LAN IP 192.168.123.20 (my server) port 8080
but it doesn't work, I keep getting my PfSense login page when I try my domain from the internet

First, Destination Address in your port forwards should not be any, but the appropriate interface address or VIP.

Second, pfSense is listening on port 80. Set it to HTTPS only and disable the port 80 redirect.

I don't have any other issues port forwarding as you can see my Plex and utorrent port forwards are working fine
I have no firewall on my server and windows firewall is turned off.
localhost:8080 displays my webpage so my server is running fine
