I've been trying to learn networking and firewalls, I've searched for most of my questions and have read some of the guides on here, so please try to forgive my noob-ness.
I've installed UTM Home edition on a spare computer without a hitch that shouldn't have any issues handling it. My current setup is:
Cable modem (Surfboard 6121) > UTM > Wireless router (TP-Link WDR3600 stock firmware). I plan to use the wired ports and a wireless network in the same LAN. I have disabled DHCP on the wireless router and no cable is plugged in to the Internet port.
However, after configuring both interfaces on the UTM, I've been unable to get out to the Internet. I've had both interfaces show Up/Up, but no output on the WAN interface. I'm not sure if I've just setup the WAN interface incorrectly or maybe it's just the firewall doing its job until I setup rules. So my questions are:
1) Can I designate my own IPs for the WAN interface/gateway? Or does it need to be what my ISP has provided?
2) Are there any default configurations that are the culprit? I know the masquerading internal > external rule is added.
A lot of text there, I apologize, just feel like I'm in over my head. Thank you in advance for any help!
