Good morning. I am new to posting in the forums, but not to reading them. I usually can find what I'm looking for, and I've done a lot of reading on my issue, but wasn't to sure if I found everything I could, so I am posting. If this is an old topic and has already been answered, please link me to area and I will continue research. Thank you for your time. I am the new IT guy with a strong background in servers and hardware. Issue came up when the company decided to move a small server farm to a different site.
I am on a "hub & spoke" network with IPSec VPN tunnels from the "hub" to the "spokes" There are five sites. Site1 has a ZyXel USG 300 and is the VPN Gateway. Sites 2 thru 5 have ZyXel USG 50. From all sites I can ping Site1 just fine. But I cannot ping Site2 from Site3 (I work in Site2 and have to remote a server at Site1 to remote a computer in Site3, 4, or 5) and since we have to move a small server farm to Site2, I need the functionality to be "mesh"
I have tried the VPN conentrator option on the USG 300, it did not work. I tried setting up routes in the routing area to and from each site, and allowed the exception in the firewall (even shut the firewall off at one point, still no ping across spokes) I think I almost had something going with a VLAN, but I dropped a site down and had to drive a couple hours to site (to the USG 300) to bring site back online. Which was not fun to explain to the boss. Person who set up the network a year ago is unreachable. He is the old IT person and left on bad terms.
I'm pretty sure something like this has been posted here before. Links to post are appreciated. But, if this is new, I can provide more information.
