I just installed a new Cisco RV042 Firewall and it has been working great. However, today I looked at the security logs and I found a lot more in there that I thought there would be. Can you tell me if there is anything that is dangerous? Also, I noticed a lot on port 137 & 138, which I have read is NetBIOS. Should I be blocking these port internally or should I just go around to all my desktops and servers and turn off NETBIOS? This log is only from the last few minutes. Thanks.
