Topology of CP VPN-1 R60 network

[Viking272]

Hi,

Please excuse my terminology...and if it's posted in the wrong area.

We have in our organisation 4 VPN gateway servers, for 4 physical sites located across the UK.
Of these gateways one is the central gateway for all communications into the company network.

VPNGATE1 -> main gateway for all traffic
VPNGATE2
VPNGATE3
VPNGATE4

So when we configure the CheckPoint SecureClient R60 client, the available gateways are all listed but only the central gateway can be selected (that works)

Our problem is that when working remotely the user cannot contact any servers that are located in the same site as VPNGATE2, VPNGATE3, VPNGATE4.Only Servers in the site that has VPNGATE1 can be accessible.

Is this a topology issue or is this a standard CheckPoint setup?

What I understand that can be done is making each gateway have the ability to authenticate with AD (via RADIUS etc) but surely we should have one gateway point into our network where every server is accessible regardless of site location?

If that is the case what are the possible changes that we can make?

Any info greatfully appreciated.

Thanks,
