I have a configuration with two providers.
For remote access clients, we changed the connection port to 8080 in the settings /Remote access -> Support Visitor Mode/. 443 port is busy for the WEB site.
The problem arises when the user connects.
If you specify in the /Link selection -> Use probing Link probing. Link redundancy mode/ menu and select two interfaces of providers. The client's configuration includes the internal gateway address, instead of those specified in the settings.
If you specify the address of one provider, the client connects.
How do we make the configuration work?
1. Setup one ISP - worked
2. Setup two ISP - not worked
3. Change Visitor Mode port to 8080
4. Configure ISP Redundancy
