ALGs
Current text:
A NAT MUST have the capability to turn off individually all ALGs it supports, except for DNS and IPsec (REQ-10)
Any NAT ALG for SIP MUST be turned off by default (REQ-10a)
Mailing list discussion consensus text for next version:
If a NAT includes ALGs, all of those ALGs MUST be disabled by default. (REQ-10)
If a NAT includes ALGs, it is RECOMMENDED that the NAT allow the user to enable or disable each ALG separately. (REQ-10a)
IPsec is not relevant to UDP
Stronger stance against ALGs being “off” by default
