I read on the Vonage site that sometimes SPI (enabling the firewall -
default) might cause dropouts and such.

I have had dropouts and one way audio (person cannot hear me at times).
My bandwidth seems great up and downstream, per my other posting.

*****My question is can I disable my SPI (Firewall) on router and still
be fairly safe (Windows XP) since I am running a software firewall
(Paid version-not Norton or McAfee)????

*****If I disable it via 192.168.1.1 should I leave any of the boxes
checked under the firewall setting such as:
Firewall Protection : Enable Disable

Block Anonymous Internet Requests
Filter Multicast
Filter Internet NAT Redirection
Filter IDENT(Port 113)

If I turn on NAT will that screw up my network (newbie question-sorry).

Thanks,
Patty

Spoke to Vonage and they put my PAP2 in the DMZ of the router. Also
changed packet size and increased buffer. Additional changes were made
by them to the PAP2 remotely. Got a good person to help me out of New
Jersey. They told me to re-enable the SPI firewall on the Linksys.
