ok i had postted this on spiceworks for this issue here: community.spiceworks.com/topic/156105-setting-up-untangle-to-replace-a-firewall?page=1#entry-918165
"ok i am trying out untangle to replace our old and outdated firewall i would to test it out with the firewall in place. i have tryed doing a network bridge with nic on the untangle server and plug my wan port to my firewall and the other one in to my switch. and when i do this i get nothing all internet stops on my network. the only thing i get is udp session no tcp sessions.."
a little in site on how to get this up and running
here is what my front end of my network looks like
gateway/modem two t1 lins in to it. > PlX515e firewall > barracuda web filter 310 > untangle box > switch\
thats what i had said for the post try some of the stuff the guy said but still not luck
"ok i tryed it again and still the same thing with it cant get online and when i look on the gui for untangle all i see for seesions is udp no tcp. i did do a settup like a router in a sens i had both port pluged in to our switch each interface with its own ip addres then i set my computer for the gateway as the untangle box and it worked fine.
i even switch the cords in revers to make shear that it was not plug in the right directions but i still had nothing.
by the way this is on a dell power edge 2950 server."
can some one shed some light on this issues so i can get it up and running on my network.
