Posted on

This is a Canonical Question about solving IPv4 subnet conflicts between a VPN clients local network and one across the VPN link from it. The remote site also uses this subnet.

Set VPN subnet translation to Enabled.

Site to site vpn same subnet. In the VPN subnet column enter a subnet of the same size as the Local subnet. In this example Vigor 2925 A is in the head office and Vigor 2925 B in the branch office and they have the same LAN network 192168102552552550. You can have the client use a dis-similar network say the 10000 or employ VPN split tunnel on the VPN server to allow client access to internet.

I have encountered this issue with XP era machines and VPN connection on same subnets. After connecting to a remote location via OpenVPN clients try to access a server on a network that exists on a subnet such as 19202024. For this example we use abc123.

The Apply NAT Policies feature or NAT over VPN is configured when both sides of a proposed site to site VPN configuration have identical and hence overlapping subnets. Navigate to Security SD-WAN Configure Site-to-site VPN. A site-to-site setup is where two or more different networks are connected together using one OpenVPN tunnel.

But you can use whatever is compatible with your VPN hardware. Create a VPN connection. Create the Site-to-Site VPN connection between your virtual network gateway and your on-premises VPN device.

Site to Site VPN DR Same Subnet. Problem is both site LANs have same LAN subnet and neither is in a position to re-IP right now. This will cause a new VPN subnet column to appear for the local networks.

Hi there is a way I can connect through a vpn ipsec 2 subnets from 2 offices with the same ip address network 192168100024 without resorting to nat or double nat. To make this work then the MX at the backup site has to connect via a stub network and then you have to have a static route via that stub which you can include in AutoVPN. You can only force all Internet-bound traffic back to your on-premises network via ExpressRoute.

The best solution is to re-IP one or the other. Ive read that Sonicwalls have an Apply NAT Policies feature on them and Im wondering if the ASA has. Follow the steps below to configure the Policy-Based Site-to-Site IPsec VPN on both EdgeRouters.

Lets say you have a layer 3 switch at the DR site you have to have some kind of L3 device. You cant enable point-to-site VPN connections to the same VNet that is connected to ExpressRoute. On both sides of the tunnel we have a Cisco ASA 5510 on IOS version 916.

In this connection model devices in one network can reach devices in the other network and vice versa. For the local subnet that must be translated set VPN participation to VPN on with translation. The OP is referring to the same subnet on both sides of a VPN tunnel which means bridging over a tunnel.

Once connected no mail or internet etc. Havent used VPN and Windows 7 yet so no experience to draw from. Good day all For one of our clients I have to set up a Site-to-Site IPsec VPN tunnel from our office building to their office building.

The IPSEC same subnet feature on DrayTek routers provides a method to link two sites that use the same subnet. Forced tunneling cannot be enabled on the Site-to-Site VPN gateway. Whilst possible its a pain in the ASS.

Site-to-Site VPN tunnel with same local subnets. In the attached image the idea would be that the server TELECAMERA 19216810010 connects to the IP camera 19216810011. If you are intending to set up a simple VPN using the Web UI refer to the Policy-Based Site-to-Site IPsec VPN article instead.

The 1921681024 and 172161024 networks will be allowed to communicate with each other over the VPN. Local network gateway name. Application Scenario – Select Site-to-Site VPN Gateway – Select the name of the VPN Gateway rule you created on the previous step Local Policy – Select the address object for the LAN subnet the local policy specifies what local IP addresses USG60 2 the nodes on the remote site USG60 1 have access over on this gateway.

Create a connection using the following values. The implementation of this is for as far as Access Server is involved in this relatively simple. However we only actually use 19216820 and above so I thought I could simply change our subnet to 1921682021 and that would free up the first 512 addresses to route to the remote site.

A VPN tunnel cannot be established if both the destination network and the local network have the same subnets. Our current local VLAN is 1921680021. Hi All I have two sites that need to connect to each other using ASAs and site-to-site VPN.

Point-to-site VPN and ExpressRoute cannot coexist for the same VNet.
