How do I bridge a VPN to a local network?

How do I connect to a network using OpenVPN?

I have a Cisco router (AVP2000V1) that I use to share the internet connection to my LAN. All I want to do is to connect to my WAN using OpenVPN, I think. I am trying to follow the steps on but it seems to be different between versions.

I did manage to connect to the internet using: openvpn --dev tun0 --remote 192.168.1 --ifconfigfile /etc/openvpn/ipsec.txt --user openvpn --passwd secret
But I am not sure how to proceed now. I am using the clientasynchttp and clientasyncnobify methods to send the HTTP request for the page. Is it possible to change what IP address to send the request from (the IP address of the router in my LAN)? Can I do this when the connection is established? If the remote IP is 192.1 then I would imagine that it has to be an IP inside the range of the interface.

If you're connecting to a VPN and the IP you are using is not inside your router then the answer would be no. You could configure your VPN to use dynamic IP but it's more of a hassle if you don't need a VPN and I don't think it works with your router.

How do I bridge a VPN to a local network?

The simplest way to bridge a VPN to a local network is to set up OpenVPN on both devices and use a common gateway for your VPN.

If you are trying to VPN into a Cisco firewall and the tunnel is working but you cannot access the internet, then check that the default gateway for the firewall is set correctly. The default gateway is the network interface where the Cisco firewall or router is connected.

Configuring OpenVPN to Use a Local Gateway. OpenVPN supports the concept of multiple gateways. This feature allows the OpenVPN client to use a local gateway when connecting to an upstream server. Using this method, you can configure OpenVPN to use a gateway on a particular network interface.

Note that when configuring a local gateway, the "server" or "gateway" section of the configuration file must match the device on the client side. Use the following configuration example for a gateway on a local network interface: The local gateway is not required for any other configuration. If you are using an application level gateway, then the following network section in the configuration is used.

For example, suppose you want to connect to a server on the following network address: Note: You can use either the IP address or the hostname. If the IP address is configured on the client side, then the server name is not required on the server side. IPv6 Support for local gateway configuration. The OpenVPN Server Configuration Guide for v3.1 uses a gatewaymode option that only works on IPv4. However, in v3.2 we have added support for the "localgateway" directive.

The "localgateway" directive is supported only if the "server" or "servername" directives are configured on the server. The "localgateway" option is ignored on the client side.

How to do port forwarding for OpenVPN?

Hey guys, I have been trying to set up a OpenVPN server.

I tried a lot of things on the server and tried to do what other people told me to do. I was not satisfied with any of the solution I had tried out there. Then I tried a few things on my side. Now I am starting to understand what I should do, how I can optimize things on the client side.

Here is what I have setup: OpenVPN Server: Running Debian. Client : Windows 7. OpenVPN Server IP : 10.2.15

Subnet Mask : 255.0 OpenVPN Client IP : 10.5 (This IP has NAT on a Windows 7 box) Here are some details of the ports that I use: 443 : Webserver for testing. 1194 : RDP ( Remote Desktop Protocol ). 1233 : MySQL Database Server. 22 : SSH. 80 : Apache Webserver. 389 : LDAP. 110 : DHCP - Dynamic Host Configuration Protocol. 111 : TFTP. 1723 : DCE. So I was able to get that my client is able to establish connection with the VPN and also communicate with the DNS Server etc. (The problem I have is that the client cannot connect to the webserver) I am aware that this is a very basic question and I hope to get a clear answer. I appreciate any advice or feedback you can give me. If there is any other information you need please let me know.

Edit: As requested here is the client config file that I am using: ; <<>> DiG 9.3-P1 <<>> 172.20.2 ############################################### www.example.com host 82.14.12 # ############################################### ;; Query time: 35 msec ;; SERVER: 172.2#53(172.2) ;; WHEN: Wed Jul 26 18:05:40 PDT 2024 ;; MSG SIZE rcvd: 104 bytes

I was also asked what the ip addresses are? Here is what I see from ipconfig on a windows machine: Ipconfig 172.2 172.1 172.
