I'm in process of purchasing a new Cisco routers for our branches that will be used primary to enable IPSec virtual tunnel interfce with "tunnel mode ipsec ipv4". does the default IOS IP Base supports this feature? or i need to purchase DATA license or SECURITY license?
View 4 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 have a Dlink DIR-825 B1 with firmware 2.05NA. I recently reset it to factory defaults to make sure I didn't misconfigure something.
I have been struggling to get a IPv6 in IPv4 tunnel working with tunnelbroker.net. I think the issue is a problem with the router itself and i'm not sure how to get it fixed.
All of my machines were getting IPv6 addresses (both windows, mac, linux) but none of them seemed to work. All I was able to do was ping the gateway itself using the local lan address. In each case they were missing a default IPv6 route. If I added a default route then it would work.
I started looking at the packets using a network sniffer and the Router Advertisements all had a Router lifetime value of "0" which is RFC4816 speak for "don't use this router as the default router". So Windows/Linux is exactly right by not setting a default route.
The strange thing was that when I reboot the router I would briefly get a router advertisement with a lifetime of 1800s, the corrert prefix and dns server but then another router advertisement would come along 5 seconds later with a router advertisement of 0.
I have TCP' Other observations
... using 6to4 I would get working IPv6 address. The difference again seemed to be the Router Lifetime. But I want to use a permanent tunnel. I have found 6to4 unreliable.
... the router never responds to router solicitations. It only sends a router advertisement when it wants to.
... the router never responds to DHCPv6 when that is configured.
I understand you can't assign an IPv4 Address to a "port". But here's my issue. I have two network cables attached to a managed switch, the location of the two cables are very important. Two computers attached to the said cables.I would like to communicate with one of the computers on PORT 1 and PORT 2, regardless of what computer is plugged into them. They get there IP's via DHCP, and a static IP wont work - as the computer plugged into PORT 1 or 2 may be different.So. I have two ports on the switch that I always want to communicate with the computer on the other end. But I don't (will not) always know the IP address of the computer(s) connected.

My own WiFi network is fine, but while I am connected to any public hotspot I get the 'no internet access' message on the wifi symbol.While connected to my own network, ipconfig/all shows that I have an Autoconfiguration IPv4 address in the (correct) 192 range - but when connected to a hotspot, the address is in the 169 range, or occasionally (as in the instance below) in the 10 range. Clearly this is the problem, but I cannot figure out what has caused it. Is it hardware? Software? Malware? Or user error?I have run the Wireless Test and the log results are pasted below.

View 7 Replies View RelatedI have a virtual machine running in my desktop which connected on the gigabit lan port on EA4500 with firmware 2.0.37.What I want to be able to do forward a port that came from an external ipv4 address to the ipv6 address and a different port to my virtual machine (to remote desktop port 3389).The reason I want to convert the traffic to ipv6 is because virtual machine is running vpn and is not reacheable through ipv4 (unless bunch of routes are setup and things get complicated etc). I verified my phsical server and virtual server get both ipv6 ip addresses through ipv6 tunnel from comcast. Without tunneling I could not get ipv6 setup using automatic mode with comcast, it simply did not work for some reason.

I'm seeing on an IOS VPN Tunnel interface which keeps going down and then back up...
We have a Cisco 2811 acting as a VPN Hub router on the backbone, which connects to various client sites over VPN. Of the 7 VPNs configured so 6 work well and are generally trouble free. The VPN interface on the other VPN keeps going down ,multiple times throughout the day, just recently the client has been noticing loss of connectivity. The remote router is managed over the VPN so there is always some kind of traffic over it.

View 3 Replies View RelatedI am preparing configuration (currently in lab) for Per-Tunnel QoS in DMVPN on ASR 1002F for one of our customers, and I came across one issue. According to restrictions for this feature, I cannot apply per-tunnel QoS in conjunction with interface based QoS. This means, I can provide shaping with hierarchical CBWFQ for each spoke, but I cannot guarantee anything on physical interface! What if there are services in native MPLS? I am also unable give reservations for BGP which is used on PE-CE link! How about monitoring spoke PE-CE links natively? I can only apply policy-map with class-default on physical interface. When I add anything related to queuing for that class (or any other non-default class) I get the message:

I have ip phones at the remote location that connect into the phone switch(it's a nortel cs1000 system) over the tunnel. Internal calls work just fine, however when somebody calls from the outside, or calls are made to the outside the connection is never finalized. Like if I call from my cell it rings the phones, but when I answer there is nothing but dead air.In the group policy for the tunnel, I gave the remote site FULL access to the phones vlan and vice versa...which obviously works since internal calls work fine. If I remove my group policy and give it the Default group policy which essentially gives that tunnel full access to everything since the tunnel is set to bypass interface ACLS, external calls work fine. So it's definitely related to the group policy.
The group policy is basicallyAllow remote site to X network/host on these ports no denies since it blocks whatever isn't specifically allowed. However since it can get the phone switch and it can get to the internet I'm not seeing why the calls aren't working.The only thing I can think of to try doing as well is remove the allow inbound traffic to bypass interface rules and treat it just like another vlan interface on the ASA. Create the rules on each interface for the remote site network etc and see if it works that way.
I've recently set up a LAN-2-LAN VPN tunnel to a 3rd party service provider who uses RFC 1918 private addressing internally and cannot perform NAT on their side of the tunnel. In order to avoid conflicts with our address space I've had to implement DNAT for the address on the 3rd party network that users at my end must access. The tunnel terminates at my end on the outside interface of an ASA-5550 running 8.4.2. While the ASA has 8 interfaces at security levels between 0 and 100, DNAT only need occur for traffic flowing from inside (100) to outside (0).
The following (redacted) addressing applies:
Address of the server on the 3rd party provider network: 192.168.2.155
Mapped address of server as seen on the network at my end: 10.168.2.155
I've currently implemented DNAT using object NAT as follows:
object network remote-server
host 192.168.2.155
nat (outside,inside) static 10.168.2.155
This works as expected, however in examples and discussion I've seen, it appears that the typical way to configure NAT for this scenario is with manual NAT as follows:
object network remote-server
host 192.168.2.155
object network remote-server-mapped
host 10.168.2.155
nat (inside,outside) source static any any destination static remote-server-mapped remote-server
Is there any reason why I should consider using the manual NAT method rather than the object NAT method in this scenario?Are there any technical reasons why using object NAT in this manner should be avoided?
I have two routers on my internal network.
10.10.199.106 is a Cisco ASA5510.
10.10.199.108 is a Sonicwall NSA 3500
The sonicwall handles our site to site VPN tunnels. The Cisco handles our client to site VPN connections.
I have a unit that points to 10.10.199.106 (Cisco) for internet access. All other clients on the network point to 10.10.199.108 (Sonicwall) for internet access.The device in question, a Synology NAS, is using 10.10.199.68 as it's IP address.
I'm trying to hit the web interface on the NAS from a remote site across our VPN tunnel. The IP scheme on the remote end of the VPN tunnel is 192.168.72.0/24.
Going through the VPN, I can hit every object on the network that uses .108 (Sonicwalll) as it's gateway. However, I cannot hit the unit that uses .106 (Cisco) as it's gateway.
I added a route statement (using ASDM) that routes all traffic destined to 192.168.72.0/24 to the Sonicwall so it can send it back down the VPN tunnel. If I'm understanding routing correctly, this should allow responses from NAS destined for 192.168.72.0/24 to go back down the VPN tunnel.
I have two Cisco 3845 routers which receive a multicast stram via a tunnel interface, i.e Tunnel163 (PIM Dense mode is enabled). These routers are both connected to a LAN segment (FastEthernet0/1/0) where receivers are. [code] Router1 is the assert winner (highest IP address), it sees igmp joins request, but it's pruning the interface. It happens sometimes and it lasts until I manually issue clear ip mroute.Unfortunately I cannot migrate to Sparse Mode.
