RV130, IPv6 DNS Server problem and VPN?

Sango

Yesterday I gotten a new RV130 and it seems to work mostly but I ran into a problem connecting to a particular VPN (using Junos Pulse) it appears to be isolated to the router itself.  When I connect, it saids I connected but it seems like the connection is dead because I am unable to ping or RDP after.

When I connect directly do my Arris Surfboard 6120 or Xfinity's supplied Arris TG862, I can VPN just perfectly.

I did notice something thou in when I look at connection details which may give a clue which is causing the RV130 to do this.  I noticed that the IPv6 DNS Servers is blank, while my own modem and the TG862 does have IPv6 DNS Servers filled in so maybe it's affecting the VPN.

Is there a way to address this?

I posted my observations of what my network card shows between using the RV130 and Xfinity below.

RV130:

Continuing from another thread, https://supportforums.cisco.com/discussion/12296966/support-dhcpv6-pd-rv180w-rv180.

I am seeing a very similar issue with the IPv6 settings on an RV220W, a blank IPv6 DNS Server field. That will mean there's no DNS Server configured for IPv6 URL lookups, and common sense would tell us this will not work.

However, I am intermittently seeing the same thing -- in an RV220W -- and while I see that same thing right now, even with the IPv6 DNS Server blank my IPv6 is working correctly, or so it seems.  I get successful results on several of those test-ipv6.com sites, even the IPv6 only http://ipv6.test-ipv6.com site.  This is where I reach the limit of my understanding, maybe the IPv6 URLs to IPv6 addresses are cached or are persisting in my PC's routing table, ... that's all I can think of at the moment.

Just curious, do you have MAC address cloning enabled to clone the MAC of the modem?

Also do you have The Cisco Small Business Support Service extended service agreement?  It looks like if Cisco were to make a firmware, you need to have this.  The reason is, the updates listed on the Cisco website are their releases vs, an update needed for your needs.

1. No. It's using the router's MAC address

2. Don't have that, am within the 12 month warranty period. If this -- beta firmware fix -- works will probably get it after the 12 months

Hi Matthew,

do you have the 192.168.1.x network on the lan and the wan of that device?  That could cause a routing issue.

Usually for successful vpn, we need an internet accessable address on the wan.

 

If you are still having problem, you can call into our support center at 866-606-1866.

Hi Dan,

The LAN and the WAN have completely different IPs.

I'll try to call the support center.
