Yes, about a year ago, I had to switch the set-up because in the auto-configuration or auto-discovery, the sme always finds the NIC card that I want to use as external first. So eth0 is the external, eth1 is internal.

It is actually a cable modem. It is an Ericsson Piperider HM200c.

I am using the sme as the gateway server. So if I understand correctly, the sme is my router. I assume that the modem is a bridge then. Not sure what a "bridge" means in this context.

I have a dynamic IP address from the ISP
> Have you switched your nic cards around?
Yes. The nic hardwired into the server died and I had to add a new PCI nic card. This new nic card is supposed to be the internal nic but the sme always discovers it first so I have had to switch them while in the configuration menu. After I get past the initial 1-2 weeks from a clean install and upgrade, I don't have any problems with this. I also didn't have any problems running this configuration under sme 5.1.x

Yes, the ISP wants us to use DHCP.

No, I don't think the modem is acting as a firewall. Maybe the ISP does do this, I don't know. I have tried to understand the DOCSIS standard so I might figure out if my ISP is blocking some ports locally or at the head end. Unfortunately, I am still a sme hobbiest and so the DOCSIS technical guides are beyond my capacity.
To reiterate, the problems that I am experiencing with the sme losing the external connection only seemed to happen after the clean install and for a week after. Then for what ever reason, it works flawlessly. I don't change anything after I have made the initial configuration except perhaps to turn on/off ssh access.

Thanks again, Paul. I appreciate any help you or anyone can provide. I realize that some of these questions or issues might be a no brainer for you guys. I am learning as I go. The sme is really excellent.
