Routing problems

OK, I give up. I thought I understood routing but I guess I don't. I am
still trying to set up a T1 firewall here at work. I am using Storm Linux
(for the first time). The following is the output from both ifconfig and
route -n:

eth0      Link encap:Ethernet  HWaddr 00:D0:B7:BF:AA:60
          inet addr:192.168.1.204  Bcast:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:5598 errors:0 dropped:0 overruns:0 frame:0
          TX packets:59 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:100
          Interrupt:10

eth1      Link encap:Ethernet  HWaddr 00:D0:B7:BF:A6:C4
          inet addr:63.88.193.147  Bcast:63.88.193.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:191 errors:0 dropped:0 overruns:0 frame:0
          TX packets:885 errors:0 dropped:0 overruns:152 carrier:0
          collisions:0 txqueuelen:100
          Interrupt:9 Base address:0x2000

lo        Link encap:Local Loopback
          inet addr:127.0.0.1  Mask:255.0.0.0
          UP LOOPBACK RUNNING  MTU:3924  Metric:1
          RX packets:824 errors:0 dropped:0 overruns:0 frame:0

          collisions:0 txqueuelen:0

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
63.88.193.0     0.0.0.0         255.255.255.0   U     0      0        0 eth1
0.0.0.0         63.88.193.129   0.0.0.0         UG    0      0        0 eth1

Currently eth0 is for the internal network, thus the 192.168.1.204 IP
address. The second NIC, eth1, goes to the T1 line which the router has a
gateway IP address of 63.88.193.129. Since we have like 40 IPs I have
selected the internal IP for eth1 to be 63.88.193.147.

I can ping any of the internal computers, but when I try to ping the gateway
or the outside world I get nothing back. What is my problem?

Thank You,
