L2L VPN on Cisco ASA with Overlapping Addresses – Access
I have just been informed by my employers IT department that my home private subnet ( 192.168.0.0/24) is the same as the one they use on the VPN at the other end of the tunnel. 1) VPN for standard client--server traffic between office and colo. Separate subnets in office and colo are OK. 2) Separate IP subnet used ONLY for replication traffic between disk arrays. Must be same subnet at both ends of the VPN. Auto IPsec VTI creates a site-to-site VPN with another USG that is managed on a different site within this same UniFi Network Controller. Manual IPsec creates a site-to-site VPN tunnel to an externally managed USG, EdgeRouter, or another vendor's offering which supports IPsec. Oct 18, 2017 · Subnets connected to the VPN cannot overlap with any subnet on a VPN peer (even if the peer's subnet is not connected to the VPN). Adam R MS | CISSP, CISM, VCP, MCITP, CCNP, ITILv3, CMNO If this was helpful click the Kudo button below VPN subnet translation allows for a subnet that is allowed in the site-to-site VPN to be translated to a different, equally sized subnet. This option is ideal for deployments where the same subnet is used in multiple locations and each of those subnets need to have access to the site-to-site VPN. When the IPSec VPN Tunnel connected, you could see entries on VPN > IPSec > IPSec SA as follows: 2. Configure Static Route on VPN Router_2. Static Route is required to make sure that packets sent from the remote subnet 192.168.10.0/24 could be forwarded to different subnets.

Configuring a separate IP Subnet for GVC Clients | SonicWall
Site-to-Site VPN tunnel with same local subnets. 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. On both sides of the tunnel we have a Cisco ASA 5510 on IOS version 9.1.6. Basically create a special network segment just for the VPN, which is entirely in a very unique subnet range (say, 172.16.213.0/24). Addresses in this range get 1-to-1 NATted to your real server IPs. So your clients would VPN in and get 172.16.213.100-254, and they'd see the servers they need as 172.16.213.50-99 for example. If the VPN is using the same subnet range as your local LAN, then the easiest fix would probably be to either change the VPN subnet or the LAN subnet (I use 192.168.0.0/24 and 192.168.1.0/24, for example). VPN Tunnel with Network on the Same Subnet. Get answers from your peers along with millions of IT pros who visit Spiceworks. I was asked to create a VPN tunnel to another one of our existing locations but I found out that the other location is on the same subnet as ours. After connecting to a remote location via OpenVPN, clients try to access a server on a network that exists on a subnet such as 192.0.2.0/24. However, sometimes, the network on the client's LAN has the same subnet address: 192.0.2.0/24. Clients are unable to connect to the remote server via typing in its IP because of this conflict. In a standard LAN to LAN network topology the local subnet at each site must be a unique network address. The primary reason for this is for routing purposes, so that it’s possible to determine if the destination IP Address can be really locally or is remote and can only be reached via a VPN tunnel, but another reason is to avoid a clash with duplicate IP Addresses, if the same IP Address
