Re: [arin-announce] IPv4 Address Space (fwd)
Right... Forgot about the SNMP breakage. SIP doesn't depend on knowing
which host it's talking to from the source address, but, it does depend
on being able to assign RTP session parameters based on IP addresses
contained within the SIP payload. Thus, when the SIP payload goes through
a NAT box and the payload is not modified accordingly, the RTP session
rarely works out right.

No. Anything that relies on knowing which host it is talking to by looking at the source address of packets breaks. Plenty of UDP based apps work over NAT.

IPSec, SIP/VoIP or almost anything that relies on UDP borks on NAT, doesn't it?-- Simon Lockhart | Tel: +44 (0)1628 407720 (x37720) | Si fractum Technology Manager | Fax: +44 (0)1628 407701 (x37701) | non sit, noli BBC Internet Operations | Email: [email protected] | id reficere BBC Technology, Maiden House, Vanwall Road, Maidenhead.
