You should have no problem running the LAN with static ip addys.
I assume Grandad's second nic is connected to the uplink port on the hub.

I assume the grandad /etc/sysconfig/network file looks
kinda like this

cat /etc/sysconfig/network
NETWORKING=yes
FORWARD_IPV4="yes"    <==============  check this
DHCP_HOSTNAME="122-237-213-120"
HOSTNAME="fw.invalid"
DOMAINNAME=invalid
GATEWAY="122.237.213.1"
GATEWAYDEV="eth1"

Now, do a cat /etc/dhcpc/dhcpcd-eth0.info on granddad

I assume you have the other two pc's dns servers set to the 
DNS=x.x.x.x., x.x.x.x.x values found in the above file,
 and their gateways set as 192.168.10.10

I have eth1 connected to cable and eth0 connected to lan

Grandads route looks kinda like this
/sbin/route -n
Kernel IP routing table
Destination     Gateway      Genmask         Flags Metric Ref  Use Iface
192.168.1.0     0.0.0.0      255.255.255.0   U     0      0     0 eth0
122.237.213.0   0.0.0.0      255.255.255.0   U     0      0     0 eth1
127.0.0.0       0.0.0.0      255.0.0.0       U     0      0     0 lo
0.0.0.0        122.237.213.1 0.0.0.0         UG    0      0     0 eth1

and the second MD system's route looks kinda like

/sbin/route -n
Kernel IP routing table
Destination  Gateway         Genmask         Flags Metric Ref  Use Iface
192.168.1.0  0.0.0.0         255.255.255.0   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      192.168.1.1     0.0.0.0         UG    0      0     0 eth0
