Remote access clients that are running Windows Vista cannot access Routing and Remote Access Service servers that use IPv6
Remote access clients that are running Windows Vista cannot access
Routing and Remote Access Service servers that use IPv6 or the computers behind the
servers.
Assume that you have used remote access policy to add Point-to-Point Protocol (PPP) connection-based IPv6
filters to Routing and Remote Access Service static filters. For example, you configure remote access policy to enable only TCP port 80 to carry traffic. In this scenario, the remote
access policy will block all traffic except the traffic that is specified in
the policy. The blocked traffic includes Internet Control Message Protocol (ICMP) v6 neighbor discovery (ND) packets. These packets
are required for clients to reach Routing and Remote Access Service servers
that use IPv6 or the computers behind these servers.
Note Routing and Remote Access Service servers that use IPv4 do
not require ICMPv6 ND packets. Therefore, this issue does not occur if Routing
and Remote Access Service servers use IPv4.
To
resolve this issue, follow these steps:
- Locate and then open the remote access policy.
- Click the Settings tab, and then click
IP Filters.
- Under IPv6, click Input
Filters.
- Add the following explicit filters to enable ICMPv6 ND
packets to be received:
- IPv6 Next header type == 58, ICMP header type = 133
- IPv6 Next header type == 58, ICMP header type = 134
- IPv6 Next header type == 58, ICMP header type = 135
- IPv6 Next header type == 58, ICMP header type = 136
- IPv6 Next header type == 58, ICMP header type = 137

Community Feedback System
Very often, it takes hours to solve a problem. Very often, you've looked high
and low, and have tried a lot of solutions. When you finally found it, chances
are, it was because someone else helped you. Here's your chance to give back.
Use our community feedback tool to let others know what worked for you and what
didn't.
Please also understand that the community feedback system is not warranted to be
correct, it's simply a system that we've built to let people try and help each
other. If something in a feedback response doesn't make sense to you, or you're
not comfortable making changes that the feedback talks about (like registry
edits), please consult a professional.
Thank you for using kbAlertz.com Feedback System.
