[PLUG] PPP Connection Problem (LONG)

I have a network setup like thus:
    Internet
        |
    Server A (10.0.0.7/255.0.0.0)
        |
      PPP modem link (10.0.0.8 - 10.0.0.9)
        |
    Server B eth0: (10.1.0.1/255.255.0.0)
        |
       LAN B (10.1.0.10 & 10.10.0.11)

Server B dials into Server A and creates a nice PPP connection. Clients on
LAN B can surf to website on Server A, however they cannot surf the
Internet (neither can root on Server B). I can "links http://10.0.0.7" and
bring up it's webpage but I can't get another server on LAN A as in "links
http://10.0.0.90".

Current settings:

Server A
eth0      Link encap:Ethernet  HWaddr 00:90:27:25:27:F8
          inet addr:10.0.0.7  Bcast:10.255.255.255  Mask:255.0.0.0

Server B Routing

Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
10.0.0.8        0.0.0.0         255.255.255.255 UH    0      0        0 ppp0
10.1.0.0        0.0.0.0         255.255.0.0     U     0      0        0 eth0
127.0.0.0       0.0.0.0         255.0.0.0       U     0      0        0 lo
0.0.0.0         10.0.0.8        0.0.0.0         UG    0      0        0 ppp0

Questions:
1) On Server B, what should the gateway be? The "far" side of the PPP
connection? The "near"? Should it be set to the Server A's gateway(which
is 10.0.0.92)?

2) Does arp present any problems with this? From Server A I can make an
ssh connection to Server B but from any other client on LAN A I get no
route to host.


Obviously I've been staring at this so long that I'm confused :-P

TIA,
Keith (Kdog)
