How do I incorporate a different VPN tunnel device behind my Sonicwall TZ210

Posted on 2015-02-12
Last Modified: 2015-02-19
I have a site that was set up with ISP managed router and a sonicwall TZ210 behind, currently establishing a VPN tunnel to my other facility.  Situation arose that I needed an additional VPN to connect to new location (fortinet).  I obtained additional Public IP from ISP, but it seems that my two VPN devices cannot run parallel because the second CIDR is somehow being statically routed to the first.  I need to get this two different VPN tunneling devices to work.  Is there a way to attached the Fortinet to the TZ210 and have it maintain a tunnel?  I really have no clue on how to get this work, and I don't understand why the ISP managed router cannot maintain the different CIDR so that my devices can route traffic accordingly.

Please help.

I do not think you need an additional IP from your ISP for a new tunnel (I do not). Nor do you need another VPN box (I do not).

Please look in the configuration of the Sonicwall for the ability to add a new tunnel to a different location (external IP).

I do this with Cisco and Juniper and multiple tunnels work great. Sonicwall most likely allow multiple tunnels.

You are right. But this new device was prescribed to me by our new parent company and I was told to make it work

I would pick one device, one IP and use that for multiple tunnels. Surely your parent company can understand this fairly simple reality.

Using multiple boxes and multiple external IP addresses into one company site just layers on complexity.  If you must do this and it is new ground for you, please get some consulting help. What you want to do is not simple.

thank you I will let them know.  I am definitely not a fan of complexity and readily admit that I am not an Engineer by any stretch.   I just dont' know at this point if the sonicwall is going to connect to their Fortinet.  I have a Parallel setup working in another facility and it works fine.  Go figure.

Thank you for the reinforcement.  I was able to plead my case on using existing device to establish additional connection
