Global Protect VPN with 2 ISP (Active Active)

L1 Bithead

Hi Guys,

 

My customer has GSLB ( 1 domain 2 ip address).

Example.  nslookup vpn.test.com 

Name: vpn.test.com
Addresses: 10.10.10.254
                   20.20.20.254

 

Is it possible to config GlobalProtect VPN with 2 ISP, 2 Portals, 2 Gateways but same certificate profile and same External Gateway name? But when client connect to each Gateway they will recieve seperate vpn ip pool.

Hi,

I faced this issue last year. Basically, GP doesn't support 2 IPs for the same FQDN... For exemple, if the first gateway is done, GP simply returns error message like 'cannot connect to gateway' and never tries to reach the second (alive) one...

You can just have 1 portal with 2 gateways…. If the portal address is unavailable then the the GP client will used a cached portal from the last known connection. It will then try both gateways and connect to the fastest responder.. ( depending on GW priority setting).  This will of course be an issue if it’s a first time connection as there will be no local cached portal. Is this for load balancing or resilience?

Some user found error like your explain.
