REMOTE ACCESS VPN FAILURE

[mbckymber]

I use a remote access VPN with a public IP and i need to switch to another IP public , and after a change i have the message failed to create a tunnel ...

Why do you need to switch to another public IP?
How precisely did you attempt to switch to another public IP?
On the gateway side, did you adjust the Link Selection setting to account for this new IP?
What version/JHF of gateway?
What version of client is involved?

Because with another IP the vpn is instable, 
i try to change on the vpn advanced the olfd for the new ip...

How can i adjust the link selection ?
version R81.10
client <E85.40

Define "instable" please..what is the precise behavior?
Please answer the question: "How precisely did you attempt to switch to another public IP?"

Usually, changing the IP used for VPN involves the Link Selection setting, which is configured on the relevant gateway object in IPSec VPN > Link Selection.
If you have more than one Internet-facing interface or NAT is being performed by a device other than the gateway, you will need to adjust this setting for VPN (Remote Access or otherwise) to work correctly.
