Ultimately the new firewall was a success and we continued to use the modem's NAT features to route all the traffic to the new firewall and proceeded to decommission the old firewall. Our solution was to just build and configure the new firewall, plug it into the modem and then log into the modem's web interface and use it's built-in NAT (which has a fairly clunky interface) to direct traffic accordingly during the testing phase. Any help or direction would be greatly appreciated. The modem is an SMC SMCD3G-CCR and is labeled as a Comcast Business Class Business IP Gateway. I'm wanting 100% of traffic to certain public static IPs to go to the specified connected firewall (I'll deal with service policies there). Keep in mind, I'm not looking to do simple port forwarding. I always understood Static Routing to refer to routing data within the LAN though, so I'm not sure if that's what I'm looking for or not. There is a 1-to-1 NAT option (which I can't seem to get the interface for it to work properly) but I also see a "Static Routing" section. I've logged into the web interface for the modem, but the available options aren't very clear. So my question is, how do I tell the modem to route all traffic that goes to a specific IP to goto the new firewall instead of the old one? The firewall switchover is going to be slow and gradual as I am testing it, so I can't simply unplug the existing firewall and plug in the new one. But in the meantime, as we will have two firewalls plugged into the same Comcast modem, I need to route certain traffic to the new firewall instead of the old one. Currently, all traffic to all 5 static IPs goes directly to the existing firewall.Įventually, obviously all traffic will goto the new firewall, once the old firewall is removed from the network. I'm stuck and need help.We are in the process of replacing our firewall, which is currently the only thing connected to our Comcast Business Class modem. There isn't an option in Sighthound to do that besides the standard 8848 port.
SMCD3G CCR SOFTWARE
I am seeing problems with other software (non-Sighthound users) with this SMC/Comcast set up and they solved it by changing the ports on the software application side. (Would it be worth putting a cheap configurable router and setup a DMZ to it so that it bypasses the SMC? Not sure whether that will work as 8080 may still be blocked from the gateway level.) Is there a solution to this? Am I missing something? There has to be someone out there in the USA that uses Comcast as their provider with this SMC modem. This tells me that bridging isnt enable until the SMC device issues a DHCP. Does work SMC - gateway SMC DHCP - 10.1.10.100 StaticIP1 - firewall. Does work SMC - gateway SMC DHCP - 10.1.10.100. Doesnt work SMC - gateway StaticIP1 - firewall. It seems the SMC is doing packet inspection and that is causing the issue. I check the ports on the computer, ports 88 are enabled. SMCD3G-CCR seems to have an issue of not allowing static IPs to passthrough.
Firewall on computer have been disabled for the purpose of this setup. I don't have double NAT so that's not a problem. Setup Port Forwarding for port 8848 to 10.x.x.x (public and private)with TCP/UDP The problem I believe is in the SMC and it's configuration and port 8080 but it's a catch 22 as I can't use that port at all (from within the SMC Gateway). Internally I can see the sighthound software by going to 10.x.x.x:8848, so I know it works. SMCD3G-CCR -> Cisco Switch (Layer 2) -> Computer (with sighthound software installed) I believe the block is in the SMC firmware. Problem is that Comcast has specifically blocked 8080 from general use as it is for their remote management purposes. I understand that Sighthound needs port 80 to work (correct me if I am wrong). I am trying to setup Sighthound to do remote access (to their security cameras) and am having problems. Jede Hilfe oder Anleitung wäre sehr dankbar.
I have a customer with a SMCD3G-CCR Modem/Router with Comcast Business with a static IP. Das Modem ist ein SMC SMCD3G-CCR und wird als Business-IP-Gateway der Comcast Business Class bezeichnet.
