Multiple DNS Names SSL Certificate

migration — Thu, 23 Jun 2011 13:45:34 GMT

Hi All,

Hope this is an easy one to answer.

I have a customer that requires that the SSL-VPN have 2 fqdn names associated with it

i.e.

https://vpn.company-A.com = 196.1.1.1

https://vpn.company-B.com = 196.1.1.1

How would i over come this as I can only allocate a single certificate to the VPN portal ?

Cheers

Marc

Hi Marc,

If they are two different companies, can they not have two portals and two IP's? Then of course different certs?

Thanks

James

They are the same company but with 2 domain names associated

With the current vpn solution they are using I think they have both certificates associated with the IP.

I will however confirm if this is the case of if they have 2 public addresses associated with their current VPN.

Thanks

Marc

Marc,

Just to clarify, are you asking if Palo Alto supports multidomain certificates, like these -

Thanks

Just as an update... have received the certificates from the CA.

Managed to get them installed eventually after some tweaking to get the certificate chains to work. the certificates had the "alternative subject name" as the second FQDN of the other company vpn and all is working as expected.

vpn.comany-a.com and vpn.company-b.com resolve to the same IP and have no cert errors.

Thanks for the help

Marc
