VPN setup questions

[jmcgon]

I am using the document for Road Warriors (https://docs.opnsense.org/manual/how-tos/sslvpn_client.html ) to set up a vpn on a Opnsense 22.7 version. 

In the setting up SSL server, the example shows using the 10.10.0.0 for the IPv4 tunnel.  From the  example it shows this as the remote works internal LAN address.  My question is that if a VPN will have remote connectors from various internal LAN's (some 192.168 others 10.10, etc) if I leave the IPv4 Tunnel unchanged or blank, will this allow remote connectors from various LAN's to connect?  Or does the remote client use the 10.10 for the ip tunnel by some default that I am not aware of?

If I set it up as per instructions, will this allow remote users to connect from various remote LAN's?

You can pick any address range that does not collide with any other you are already using somewhere in your network. Nothing hardwired here.

Thanks. 

Another question.  Setting up vpn server how does one decide which compression protocol to select?  Does it matter as long as it is enabled?

Its NOT recommended to run compression at all.

There are known security issues with compressions, I strongly recommend compression none.
