Ok, here goes:
This is the first time I've fooled around with LVS/UltraMonkey, so I would really appreciate it if seasoned LVS/UltraMonkey veterans could chime in. Currently, this is how my network is setup:

I am currently testing my setup on my Road Runner cable modem setup, and also using AOL on top of my cable connection to test the setup from 'outside' of my network (since apparently the IP address when surfing via the AOL IE browser is different than my public IP address - I have another PC hanging off of the switch that is not displayed in the diagram). I have 1 director, and 2 real servers at the moment. I have my firewall/NAT router point to 192.168.123.182 for all http requests. When I access my site via my domain name (accesses the public IP) from outside of my network (using my AOL IE browser), my browser seems to take awhile to load (website found, waiting for reply), then gives me a '502 Connection Hangup' error message. When I use my cable modem to access my site (it goes out and searches for the URL, but when it reaches my router, I assume it gets forwarded to 192.168.123.182, and displays my site just fine. So basically, I can access my site fine locally, but no one outside of my network can see my site. What could I be doing wrong?
The director is currently running RedHat 7.2 with the 2.4.7-10.um.1 kernel. I have loaded up the UltraMonkey (v2.0.0) scripts and when I run ipvsadm -Ln on the director, I get the following:
