et me illustrate the scenario a bit.
I have a computer with Check Point installed and 2 NICS. (1 NIC with the legal ip address from my ISP and the other ip address for my internal LAN). I'm using a DSL modem and getting a dynamically assigned IP address from my provider.
I have a connection running from the DSL modem to the NIC card that has the IP address given to me by the ISP. I have the other connection running from the 2nd NIC to a switch. My other computer is also connected to the switch. I put the legal IP's address in the gateway and can ping the other computer's internal address but not the legal IP.
My Check Point rule base is simple with the following rules:
1) Stealth rule dropping any packets coming into the firewall from the outside
2) Allow all traffic within the internal LAN
3) Cleanup rule to explicitly drop all other traffic
I've verified this rule base and installed it with no errors.
I still can't figure out though why I can't get to the internet on the 2nd computer.
Any ideas?
Also, I'm not sure if I have the IP settings correct on my 2 computers. The computer that has 2 NICS and is running Firewall-1 has a configuration similar to this:
COMPUTER #1 (Check Point) COMPUTER #2
NIC# 1 NIC
IP Address: 151.204.137.42 IP: 192.168.129.3
Subnet Mask: 255.255.0.0 Subnet: 255.255.255.0
Gateway: 151.204.137.42 Gateway: 192.168.129.5
PPP ADAPTER
IP Address 151.204.137.42
Subnet Mask 255.255.0.0
Gateway 151.204.137.42
NIC# 2
IP Address 192.168.129.5
Subnet Mask 255.255.255.0
Gateway 192.168.129.5
I can ping to and from the 2nd computer but can't get to the internet.
Do I need a 2nd valid ip for this setup to work? I'm pretty sure my very short rule base is correct. Any ideas? Thanks in advance!
