Both VPC1 and VPC2 have a subnet with the same CIDR (10.3.3.0/24). VPC2 VMs need to access both VPC1 and VPC3 VMs in their 10.3.3.0/24 subnets. Since VPC1 VMs may change their private IP addresses after some unplanned reboots, VPC2 VMs have to access them through DNS.
Solved: ASA VPN with overlapping subnets. - Cisco Community Hi, Lets assume that 10.1.1.0/24 is the overlapping subnet on both ends of the tunnel. nat (inside, outside) source static obj_10.1.1.0 obj_10.2.2.0 destination static obj_10.3.3.0 obj_10.1.1.0 This nat rule will translate 10.1.1.0/24 on site A to 10.2.2.0/24 and site B is being set up to pose as Overlapping VLSM Subnets - Tutorial Overlapping VLSM Subnets. Subnets chosen to be used in an IP internetwork design must not overlap their address ranges. With a single subnet mask in a network, the overlaps are obvious; however, with VLSM, the overlapping subnets might not be as obvious. When multiple subnets overlap, a router’s routing table entries overlap.
Hi, I wonder if someone could help me here. If I have multiple VRFs defined on a switch that extend to respective context on the Firewall. I have following questions regarding this setup 1. How can I access one VRF from another if they have overlapping subnet e.g VRF_A and VRF_B both using 192.16
A VPN tunnel cannot be established if both the destination network and the local network have the same subnets. 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.

Subnet overlaps another Network? | Yahoo Answers
Dec 27, 2010 · Will AD understand if I just enter 10.22.1.0/24 as a site subnet or do I have to break the entire 10.0.0.0/8 definition down to individual subnets. I know in IP routing, when a subnet can fit into two routes, the most specific route is used but I wasn't sure if AD understood the concept of most specific definition when there was overlap. In the above case both the sites Subnets are overlapping. (LON is having a IP subnet which is sub set of US IP subnet) In this scenario, when a machine boots from LON site, how it will decide to Use this calculator if you have a list of IP addresses or IP ranges you want to sort, deduplicate, or ensure that another set of IP ranges is excluded (e.g. whitelist / blacklist). The calculator will evaluate the shortest possible representation of the these IP addresses as network blocks. SSL VPN enables us to easily get to the corporate SonicWall LAN subnets over the web with secure VPN tunnel but sometimes due to overlapping of SonicWALL LAN subnet and IP of client, we are unable to access the LAN resources. Follow these steps: 1. To create address object for SSL VPN IP tool. In the folloing topology, both spokes have the same subnet that needs to be protected over the IPsec tunnel towards the Hub. To facilitate the management on the spokes the NAT configuration to workaround the overlapping problem is performed on the Hub only. ASA1 Create the necessary objects for the subnets in use Jan 30, 2015 · The challenge with overlapping subnets is in routing. In the above diagram, ASA1 has a direct connection to the 192.168.1.0/24 network via its inside interface. Therefore, there is no way the ASA will forward traffic for the same subnet out of its outside interface towards ASA2.
