I'm running Windows 7 Ultimate 64 (have NOT installed SP1) with ESET Smart Security 188.8.131.52. My trusty Netgear FVS318 firewall/router died, and I replaced it with a new Cisco RVS4000 Security Router/firewall. I'm not able to browse the internet, send/receive email, etc unless I disable the ESET Firewall. This worked fine for months with the Netgear box, but immediately on installing the Cisco device my internet browsing stopped. Is there some configuration changes I must make in order for these to work together? Or should I permanently disable the ESET firewall (and if so, how do I do that)? Note I've also disabled the Windows Firewall.
