My Office firewall (Sonicwall Pro 2040) block everything from my homeoffice
Posted on 2006-05-18
After I installed my new firewall (sonicwall pro 2040) i have problem getting through to my office. The sonicwall find every connection/attempts from my homeoffice as an intrusion, eighter it's a request for a webpage, ftp server or terminal server. The log says it blocks the request because the category is "intrusion prevention" and message "ip spoof dropped" with the explanation "striker attack". I don't have this problem from any other locations, and can't figure out why this happends. My homeoffice firewall is an cyberguard sg530. There is no rule in eighter firewalls that attempts to rewrite the packets.
