VM HUB3 incompatible with VPN operation!

When I started with VM I had 10Mbps Broadband and a HUB2.  Gradually they upgraded my speed I am now on M125 100Mbps.  Still on HUB3.  This is fine for me on my home user working.  However I am a volunteer at a local charity.  They use Active Directory on the internal network and Azure IP etc..   We have file shares on the internal network.  We use Checkpoint VPN to tunnel into the internal network.  But it doesn't work with this HUB3 that is not a good router - very locked down.  The VPN ethernet client will channel ALL network traffic down the tunnel to our internal network. Use the DNS server associated with AD so that I can set up the file shares on the file server.  Any internet traffice it will route out via the charity Firewall.  They can deal with security aspects of that.  But HUB3 doesn't allow this.  Does HUB4 or HUB5 provide a better internet router.  (Maybe they will allow me to use the Private address space 10.0.0.0 - which HUB3 doesn't - how pathetic).  If I am on Gigabit 1 broadband I can claim a free HUB upgrade.  But is M125 or M25 Gigabit 1??  It must come over a 32Gb fibre bearer surely.  The more I deal with VM the more I feel they are not a professional communications company but a Media company more interested in selling me TV etc... Sorry but I have changed my Email service away from VM in the light of the recent serious outage.  I am not trying to be negative BUT to use my PC and networking professionally with a good VPN client and a very tight Internet Security/anti-virus protection.  Any help you professional forum users.  Thanks
