In the routing table for IPv4 or IPv6 networks, when we are connected to a VPN server with traffic redirection, the default gateway should appear with the corresponding route to the entire local network and the different subnets of the different network interfaces that let’s have.

1.1 which is our router, and interface 10.11.1.2 is our IP. As you can see, what the first route does is forward all the traffic to the default gateway: network destination 0.0.0.0 (any), mask 0.0.0.0 (any), and the gateway is 10.11.
Openvpn redirect gateway how to#
TL DR everything breaks with OpenVPN and squid and I'm not sure how to fix it.In the routing table for IPv4 or IPv6 networks, when we are connected to our home router, the default gateway should appear with the corresponding route to the entire local network and the different subnets of the different network interfaces that we have. If I reinstall squid, something resets and the internet is accessible once again but everything goes through the WAN gateway, VPN not routing anything.
Openvpn redirect gateway install#
With 3, I get an http invalid request on every device on my network (10.1.1.0 and 192.168.1.0) when I first install squid. With 2, all traffic goes through the VPN gateway, no selective routing. With 1, all traffic goes through the WAN gateway, VPN not routing anything. Once I install squid (I select vlan3 and LAN interface and check transparent proxy) and here are the results: However, this is without considering squid. TL DR option 3 is the only one that routes everything correctly as per my original post. Regardless of if I put or leave out 10.1.1.0/28 into the remote tunnel section but put route 10.1.1.0 255.255.255.240 vpn_gateway in the advanced section, then the 10.1.1.0 vlan is getting pushed through the VPN and the 192.168.1.0 can access the WAN. However, I can't access my default ISP WAN with the 192.168.1.0 network.ģ. If I put 10.1.1.0/28 into the remote tunnel section and 'redirect-gateway def1' in the advanced section, the 10.1.1.0 vlan is getting pushed through the VPN. If I put 10.1.1.0/28 into the remote tunnel section and no 'redirect-gateway def1' and no 'route 10.1.1.0 255.255.255.240 vpn_gateway, then the default ISP gateway is used on the 10.1.1.0 vlan.Ģ.

Without squid installed at all, here are more details:ġ. I'm trying to split my network into different vlans and route the vlan subnet 10.1.1.0/28 over the StrongVPN and leave 192.168.1.1/28 default vlan, my LAN, off the VPN and put both on squid. Yes 10.1.1.0/28 is a local vlan I created. I thought that was the network you were wanting to reach via the VPN. So you are saying the remote end is blocking the LAN subnet IP? How do I fix I misunderstood what you were saying about that 10.1.1.0/24, you don't want that specified anywhere in the OpenVPN config since that's a local network. I didn't fully understand what you wrote. If I leave out the redirect-gateway def1 flag, then the entire network is routed out the WAN. When I have squid set for transparent proxy, the entire network is routed through the VPN. In addition, I am using the redirect-gateway def1 flag in the advanced section of the openvpn client. I made the change you suggested by using remote network. The remote end blocking that IP (or not having proper routing for it or something) but allowing your LAN subnet is the most likely cause. Squid makes the requests out, and initiating traffic from the firewall itself makes the source IP the interface IP that's closest (by the routing table) from the destination, which is the tun interface IP rather than an IP on your LAN subnet. The difference between Squid and direct is probably only the source IP.
Openvpn redirect gateway code#
Put it in the "remote network" and our code makes sure it's handled correctly on the back end now and in the future. Still recommend changing the route as I described, as if that works, it's only by coincidence.
