Hi Suresh,

I modified both 13.2 and 13.3 sections. The text I proposed is for 13.3 (IPv6-to-IPv4 Translations). For Section 13.2 (IPv6-to-IPv6 Translations) used the following text:
If the ICMPv6 packet ("Packet too big") is being sent to the peer, the TURN server reduces the MTU reported in the ICMP message by 48 bytes to allow room for the overhead of a Data indication.

Cheers,
-Tiru

Hi Tiru,
  Thanks for addressing my comments. Your suggested text changes look good to me except one. The open point inline.

* Section 13.2 Page 53

"If the packet is being sent to the peer"

The term "the packet" is ambiguous here. This could potentially refer to the
ICMPv6 packet being sent or the original packet that caused the error. Can
you please clarify which one you mean here?

Fixed text for clarity as follows:
If the ICMPv4 packet (Destination Unreachable (Type 3) with Code 4) is being sent to the peer, the TURN server SHOULD reduce the MTU reported in the ICMP message by 48 bytes to allow room for the overhead of a Data indication.

This text will not work. It is an ICMPv6 packet that will be sent and not an ICMPv4 packet. Can you reword with ICMPv6 Packet Too Big instead.

Regards
Suresh
