sorry - been away for work.
I am trying to get the SG1100 to work as a transparent firewall....but for whatever reason as soon as i configure it as per the instructions on the netgate forums - it stops working.
So - i guess the real question is - can the SG1100 ACTUALLY be used as a transparent WAN-LAN firewall without NAT- i.e
Cable Router - Wan SG1100 - firewall bits n pieces (No NAT) - Lan out - internal router (NAT)
WITHOUT NAT - as i would prefer my internal router to do NAT - i dont have any issues with it working now - so id prefer not to change as i have everything working fine.....i literally just wanna throw the SG1100 in front so i can use PFBLOCKER, etc to try and get rid of some of the everyday crap bombarding our devices, and so i have a VPN endpoint for work.
As my cable router is ISP Dynamic IP - how is the SG1100 able to get the upstream router when its dynamic in that circumstance. I think this is where the problem is - because we dont get assigned static upstream IP's....the SG1100 has no idea where to send it - because there is no way for me to get the upstream router details.
Any help would be great.
