Hello all, Some quick questions on anti-spoofing and sendmail. We were using and IDS script to send e-mail alerts from our firewall (4.1). We recently activated anti-spoofing on the firewall's interfaces and the mail no longer arrives. In the fw log I noticed that sendmail was using the address of the firewalls external interface as a source address and was therefore dropping the packets (rule 0 - spoofing). Anti-spoofing on the internal interface was configured with "This net", so I created a group containing the Internal network object and a new workstation object I created giving it the firewall's external interface IP and set this as the "Specific" valid address. The packets still get dropped on rule 0 - spoofing. Does the firewall service need to be restarted for spoofing rules to take effect? Is there something else I'm not thinking about? Thanks!
