two modems issue

Hello,

We have a netwerk (server 2003's and Windows XP's) with two sdsl-modems. One
Mailserver and one Dataserver which can connect to each other. The
mailserver is getting the mail through modem one. You can reach the
Dataserver by VPN through modem two (vpn-connection between home modem and
work modem). Everthing works fine, there is only one
problem, the VPN users can't reach the Mailserver. That is because the
gateway of the mailserver is pointing to modem one.
Is there a way that the VPN users can get to the Mailserver ? We don't want
to open a port on modem one, so the solution has to be through VPN (modem
two). May be with a router or a change on the routing table on the
Mailserver ?

Greetings,

Marty

It sounds like routing issue. We need more information to help you, for
example all IP addresses and subnets.

Hallo Robert,

I will try to make it more clear.
It is a network of 60 pc's and 5 servers, but that would be to difficult. I
concentrate me on 2 servers. Server1 uses modem1 and server2 uses modem2.
(Server1 is mailserver and server2 is dataserver and they can reach each
other because they are on the same subnet). The users at home do have a
vpn-client or a vpn-modem to contact to modem2 (vpn-modem). When they
contact modem2 they can go to server2 and use the data on it.
And now the problem: If you get with vpn to modem2 you cannot reach server1.
You cannot reach it because server1 cannot talk back to you, because server1
sees you are from outside and server1 wants to go back to you using it's
gateway. BUT, the gateway is pointing to modem1.
The same problem is when you use Remote Desktop when you are at home. You
can go through modem2 and reach server2, but you cannot use server1, because
the gateway of server1 is pointing to modem1 and server1 can't talk back.

Modem1 Modem2 (vpn)
Server1 Server2

I don't want to open ports on modem1 to get to server1 from outside and I
don't want to change the modem1 to a vpn-modem.

I hope this is clear enough. Please let me know if it isn't. It is not just
a problem of this network, every network with two modems will have this
problem. I just don't know the solution for this type of problem.

Hope you can help,

Marty

That makes sense if the VPN client is not in the same subnet as the LAN and
route won't be able to return. You may have different options.

1. Re-configure the VPN to use the same subnet as the LAN.
2. Add one route on the server1 to point the VPN client. This search result
may help.

RoutingAnalysis 1: before changing the route table, any computers in
192.168.2.0 can access the resources on 10.0.0.0 network and the Internet
because all traffic ...

Hello Robert,

Thanks for your help. The vpn clients can use directly 4 servers (RDP via
vpn). Server number 5 they can't reach. That is also the only server with
the gateway to the other modem. The vpn is the same subnet as the network. I
can reach the 4 servers with Start-Run \\ip-number and with Remote desktop.
Server 5 I cannot reach. I can reach server 5 from one of the other servers,
so, remote desktop is working and start-run \\ip-number also.
I know, it makes no sense. I would say also that the servers won't even use
gateways to reach the client because they are on the same subnet.

I am sure you must be right, but I can't find the solution. There is no
firewall on the servers, the subnet is the same, the routing table on
server5 looks fine to me.
I have to find the solution.
You helpt me a lot, I am now sure the servers won't need a gateway. I tested
it on another network without gateway and it worked fine.

Marty

I already dealt with this in the other groups you asked in. Please do not
multi-post. Corss-post instead so it is the same message to multiple groups
so that when someone replies the reply shows up in all the groups that is it
in.

Hello Philip,

Sorry, but in one of the groups I waited and nobody answered, so I thought,
may be it is the wrong group I posted it in.

No problem. It was just a FYI. A lot of people aren't aware of how the
groups mechanically function.

>>>>> Hallo Robert,
>>>>>
>>>>> I will try to make it more clear.
>>>>> It is a network of 60 pc's and 5 servers, but that would be to
>>>>> difficult. I concentrate me on 2 servers. Server1 uses modem1 and
>>>>> server2 uses modem2.
>>>>> (Server1 is mailserver and server2 is dataserver and they can reach
>>>>> each other because they are on the same subnet). The users at home do
>>>>> have a vpn-client or a vpn-modem to contact to modem2 (vpn-modem).
>>>>> When they contact modem2 they can go to server2 and use the data on
>>>>> it.
>>>>> And now the problem: If you get with vpn to modem2 you cannot reach
>>>>> server1. You cannot reach it because server1 cannot talk back to you,
>>>>> because server1 sees you are from outside and server1 wants to go back
>>>>> to you using it's gateway. BUT, the gateway is pointing to modem1.
>>>>> The same problem is when you use Remote Desktop when you are at home.
>>>>> You can go through modem2 and reach server2, but you cannot use
>>>>> server1, because the gateway of server1 is pointing to modem1 and
>>>>> server1 can't talk back.
>>>>>
>>>>> Modem1 Modem2 (vpn)
>>>>> Server1 Server2
>>>>>
>>>>> I don't want to open ports on modem1 to get to server1 from outside
>>>>> and I don't want to change the modem1 to a vpn-modem.
>>>>>
>>>>> I hope this is clear enough. Please let me know if it isn't. It is not
