Windows 7 - Win7 through a PIX 506 firewall

| | Win7 through a PIX 506 firewall I've got a Cisco PIX 506 firewall that only allows traffic to certain sites with my PCs running Windows 7 on my small office network. I'm sure it's a firewall issue as I've disconnected the firewall and went directly to my ISP (Cox) and had no problems. What settings must I change on my firewall or on Windows 7 to get it to work with my PIX 506? |

| | I think the issue is related to the Scaling where it tries to auto-tune teh MTU. |

| | Thanks for your reply. I'm not an expert so can you direct me as to how I could check this or make a change? I know MTU has to do with packet movement but is that changed in Windows 7 or on the firewall? Thanks! |

| | Try this open an elevated CMD prompt, then type: netsh int tcp set heuristics disabled <enter> netsh int tcp set global autotuninglevel=disabled <enter> See if that helps |
