[HowTo] Mod Security on debian

[r3r3]

Hello
I am getting this error

Code:

[Tue Dec 23 15:14:06 2008] [error] [client 127.0.0.1] ModSecurity: Access denied with code 400 (phase 2). Pattern match "^[\\d\\.]+$" at REQUEST_HEADERS:Host. [file "/etc/modsecurity2/modsecurity_crs_21_protocol_anomalies.conf"] [line "60"] [id "960017"] [msg "Host header is a numeric IP address"] [severity "CRITICAL"] [tag "PROTOCOL_VIOLATION/IP_HOST"] [hostname "127.0.0.1"] [uri "/"] [unique_id "Y2ErmAoCApQAAAj1GDIAAAAT"]

Should i do something about it? It's obviousely my own server's localhost ip which is blocked by modescurity, anyone can advise what to do?
