The owner has an IPSec Tunnel to their main office and we want an IPSec tunnel to our main office. &nbsp;We have our own VLAN at the remote office, which corresponds to a VLAN here. &nbsp;We are currently using a DCB Net 3302 and 6602 for the tunnel, but are looking to replace this using IPSec.<br />
<br />
We are using MikroTik's EoIP (Similar to GRE), with OSPF, IPSec, MPLS and VPLS.<br />
<br />
Thanks for the information. &nbsp;Will be at the remote site on Thursday with their IT department and will see what we can figure out.

<div>
Most mid-level VP routers allow multiple tunnels. See what you find, but economical VPN routers exist that allow multiple tunnels.

<div>
Multiple tunnels can be set up as described in the solutions provided.

We have a remote site, which is currently using pfSense as it's firewall. &nbsp;There is one static IP, the ISP isn't able to add additional IP's with out changing the IP range, no surprise there. &nbsp;This site is owned and operated by a vendor and they are not willing to move IP's since it will require a reconfiguration of their network. &nbsp;The owner is already using IPSec to connect that office back to it's main office.<br />
<br />
We have some computer equipment in the remote office and would like to upgrade our network equipment and ideally would like to use IPSec. &nbsp;While I could move IPSec to another port, the issue is with GRE, as there isn't any real port used.<br />
<br />
Are there ways to configure multiple GRE/IPSec tunnels over the same Static IP with different physical hardware?<br />
If so, how?<br />
If not, what are my options? <br />
<br />
For our equipment I'm using a MikroTik CCR1016-12G<br />
<br />
Thanks in Advance.

Multiple IPSec Tunnels one Static IP?

Hardware-based firewalls provide more sophisticated protection for inbound and outbound traffic than the simple Windows software firewall or the basic NAT firewalls found in routers. These devices implement techniques such as stateful packet inspection, deep packet inspection, and content filtering; and may include built-in antivirus and anti-malware protection.

Hardware Firewalls

Internet Protocol Security (IPsec) is a protocol suite for secure Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session. IPsec includes protocols for establishing mutual authentication between agents at the beginning of the session and negotiation of cryptographic keys to be used during the session. IPsec can be used in protecting data flows between a pair of hosts (host-to-host), between a pair of security gateways (network-to-network), or between a security gateway and a host (network-to-host). IPsec is an end-to-end security scheme operating in the Internet Layer of the Internet Protocol Suite.

Internet Protocol Security

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
