![]() How to Setup IPsec Tunnel between Paloalto and PFsense? I am using a cisco vios router for this lab, any other cisco router would work just fine as well.īuilding this IPsec lab is very easy, you just have to follow each step that I mentioned here and you should be good to go. In the end, you need to configure the topology like I shown below and everything should work just fine irrespective of the platform. Some users use cisco CSR1000v routers on VMware ESXi or KVM hypervisors to do the lab, if you have that as an option that is also good, you can just follow along. I am building this lab on GNS3, since gns3 supports many of the Cisco IOS router software you can easily spin up cisco routers on GNS3 and configure IPsec site to site VPN on Cisco IOS software on GNS3 itself. That’s why many users prefer to use virtualized solutions such as gns3 or eve-ng and even other hypervisors. The problem with that approach is that it is way too expensive. If you wanted to build a network lab some users prefer to have physical gear. Can I set up IPsec VPN on cisco routers using gns3? The only requirement for the IPsec tunnel setup is the internet and the supported hardware. Moreover, the internet is getting cheaper and cheaper, so why buy expensive dedicated link, rather we could use the same internet for the branch connectivity. So IPsec is the go-to solution by many enterprise users. If you just start sending a packet over the internet without encrypting, some bad guy on the internet can sniff your data. ![]() So if you use IPsec between the branch offices the data send between the sites will be encrypted. By default IPv4 or IPv6 do not provide security. The main reason we use IPsec VPN is to provide a security mechanism on an insecure medium like the internet. The IPsec site to site VPN is mainly used to connect between different branch offices over the internet, the branch could be a small office to bigger ones, even a coffee shop or an ATM. Why should I use IPsec Site-to-site VPN on Cisco routers? How to check IPsec tunnel status in the Cisco router?.Setup the lab topology for IPsec configuration. ![]()
