Can Pure IPv6 Host Ping A IPv4 Host?
Feb 10, 2011I'm just wondering if its possible to ping an IPv4 host using the IPv6 host assuming that the NAT64 has already been implemented?

When I try to ping ipv6.xsnews.nl on either of my Windows 7 computers, it returns "Ping request could not find host". But when I do it on XP, it succeeds. I have tried putting the W7 PC in the DMZ, disabling the software firewall but it doesn't work.
What I think it involves is having ipv6 installed on each. I tried to duplicate the setup of both the XP and a W7 computer, installing the gogo6 tunnel. But apparently it's not setup on this computer because the ping result is the same as on the third computer which hasn't had ipv6 installed. s not setup on this computer because the ping result is the same as on the third computer which hasn
I have a host that can successfully connect to a PIX 515E (7.x OS) via VPN Client; however, I have no IP routing to the LAN from the remote host.The VPN IP pool works finem,The LAN default gateway is the inside interface on the PIX; the network is flat L2 behind it.The default route on the PIX points out; no other routes are defined,The VPN remote host can be pinged from LAN hosts, but the VPN remote host cannot ping any LAN host, not even the PIX inside interface.

I have been looking all over the place for the answer of how to allow clients on an IPSEC VPN to ping from host to host.
I set this up and I can ping all the gateways but never the hosts. I was hoping I could make these links between 6500's a mix of L2 and L3. Check it out. They are connected in a linear fashion R1--->R2--->R3. I can ping from R1 to R3's SVI4 gateway but I can never ping a host on that SVI4. I was hoping that I could use the port-channels between 6500's as routed links or as trunk links depending on the type of traffic....thought it would ease the migration. I suppose I could always get rid of the port-channels and just make separate L2 and L3 links between the 6500's.

When I tried to ping [site], I get: "Ping request could not find host [site]. check the name and try again." This happens regardless of the site I use.Lastly, I tried "ping 127.0.0.1" from a troubleshooting site. It gives me: "Pinging 127.0.0.1 with 32 bytes of data:

ASA 9.0: nat (LAN, outside) 85 10.252.253.123 source static 192.168.3.2 192.168.3.2 192.168.3.104 static destination service http http In this form the host 192.168.3.2 uses the mapped ip (192.168.3.104) to access by http but unlike before now I cannot access to the original IP (10.252.253.123) using another port or ping from host 192.168.3.2.
From the router I can ping the 2nd router, all its host and all of the 1941w interfaces.
From the 1941w AP i cannot reach the 2nd router or any of its host, but I can reach the interface that is connected to the 2nd router but only one side of it.
Attached are both my router and ap configs. At the moment I am just trying to reach the 2nd router and its host so I can update the AP IOS image but cannot reach the tftp server.
I am in a test environment using an ASA 55005 and a Cisoc 2611xm router. ASA is running version 8.4 and router is running is ios12.4. My VPN tunnel comes up but I am unable to ping between remote hosts. I used the ASDM and SDM for the configuration. Attached is a copy of both configs.

I've just want to confirm if I can protect a router (telnet and ssh) putting 2 ACL's (one IPv4 and other IPv6) on the same line vty. Something like:
line vty 0 4

ipv6 access-class hostsIPv6 in
Do I have to use named ACLs?
our company backbone is hp 5406, and desktop switches are hp 2510 currently we are working with ipv4.if we want to start use IPV6 for test environment, what’s things we need to enable in our backbone/regular switches.i mean for example if we want to set static IPV6 address for 2 servers and send ping between them, or even make new vlan with IVP6 subnet, and use it like regular vlan but with static ip's(until we got ipv6 dhcp).i have hp 5406 manual for IPV6 but i can't understand what i really need to do for start using IPV6.
View 5 Replies View RelatedRecently I wanted to setup IPv6 for my home network. I signed up for tunnelbroker.net service and was provided with IPs. Then I configured the IP address in my DIR-615. But It's not working..
Screenshot of IPv6 config (router) : Screenshot of my Win 8 network Config : I also tested at [URL] but failed...
I currently have ipV4 as the setting on my DIR-825. Other posts seem to want ipV6 which is more secure but is not possible with a DIR-825 Rev A1. I have two routers, a primary router (DIR-825 Rev B1) capable of ipV6 and a secondary router (DIR-825 Rev A1). If I implement ipV6 on the Rev B1 router but keep ipV4 on the secondary router, will this improve the security, or will it just mess things up so nothing works?Certain devices (cell phones and most Tablets) don't deal with ipV6 very well at all. The ones I have tested flat don't connect to the wireless network if the router is set at ipV6. Is ipV4 adequate for a Home/Small Business Network when trying to implement Remote Access and VPN?

Is it possible to do static (inside,outside) with the outside address being IPv6 and the inside IPv4?
If yes, is it possible to do this in parallel with an existing static mapping that goes IPv4 to IPv4?
