Description | This article describes methods to choose SIP-ALG and Session Helper. |
Scope | SIP ALG/Session Helper. |
Solution |
By default, FortiGate is using SIP ALG to process SIP traffic however some SIP providers recommend disabling SIP ALG in the firewall.
Proxy-based – default SIP ALG mode
Below are points that need to be understood:
If proxy-based is selected which is a default mode, then no matter if session helper is configured, ALG mode supersedes and session helper is doing nothing.
Example:
- For traffic inspected by a helper, debug flow shows:
run helper-ftp(dir=original)
# diagnose debug application im 31
