View 1 RepliesI cannot ping mydomain.local from any computer on my network. In order to this, I have to set DNS 1 as my server's ip address, then I can ping it. The reason this is a problem is because in order to add a workstation to my domain, I have to manually configure DNS to my server's ip. I have two networks, all new systems and this occurs on both. So obviously it is the way im setting things up[CODE]

I have noticed that my virtual-access interface comes up but the line protocol of virtual-interface remains down as follows:
Virtual-Template100 x.x.x.x YES TFTP up down
Also The client PC picks up a random gateway of 10.10.10.1 which I never configured anywhere on the server.
I have, what I believe to be, a simple issue - I must be missing something. Site to Site VPN with Cisco ASA's. VPN is up, and remote hosts can ping the inside int of ASA (10.51.253.209). There is a PC (10.51.253.210) plugged into e0/1.
I know the PC is configured correctly with Windows firewall tuned off. The PC cannot get to the ouside world, and the ASA cannot ping 10.51.253.210.
I have seen this before, and I deleted VLAN 1, recreated it, and I could ping the local host without issue. Basically, the VPN is up and running but PC 10.51.253.210 cannot get out

Ive got my home lab setup with two 2610 routers hooked togeather with a DTE/DCE Crossover and I have OSPF configured on both routers. Each router has one 3550 switch connected to each FA0/0 inteface. The issue is that Everything can be pinged except my windows 7 PC connected to the R1 LAN. Everything else can be pinged from any other device. I checked the PC gateway configuration, disabled the firewall and checked my switch configuration! Is their something that I need to change in Windows?
Windows PC ------------ 3550 Switch-------------R1-----------------------------------R2---------------------3550 Switch----------------------Linux Box
Windows PC can't ping past the FA0/0 interface between the switch and R1

View 2 Replies View RelatedI have a setup with a few sites that have layer three switches behind firewalls. I've been successful in setting up GRE tunnels between all the layer three switches, the GRE traverses IPsec which goes between the firewalls at each site. That way, the GRE is encrypted over the Internet and I don't have to deal with protocol forwarding and stuff. The GRE tunnels are terminated at the loopback addresses of each layer three switch, this works well for the most part, except that I need to put static routes for each loopback address in each switch to point via the firewalls, because when OSPF comes up over the GRE tunnels it starts advertising the loopbacks, and as such the switches think they can get to them over the GRE (which is built from the loopbacks to begin with), as you can see, sort of a catch 22. The static route method works fine, but it makes it so that I can't access the loopback address for monitoring/management purposes from any other sites on the basis that the local core tries to send it directly to the firewall rather than over the GRE tunnel. Is there any way to force only the GRE traffic out via the firewall while letting any other loopback-destined traffic go over the GRE? I'm thinking this could be done with a properly-matching route-map, but I'm not sure where I would apply it, could I apply it directly to the loopback or would the GRE traffic skip that on the way out?

This is one of the standard issue vodafone routers. So i set up web-server on my laptop, and it is accessible to the internet now.
However I need to be able to access it from my machine using the public address. But I just cannot find where to enable nat loopback. I looked for options in both regular and advanced user logins (web interfaces). So I suppose the last option is telneting into it, and using commands to do it.. but I don't know how to access it (cant find the credentials). URL
In above link it says that i can find this info in configuration file, but how to access it?
And then what commands should I use to enable the NAT loopback?
In my home network, I have a Synology.

AT&T yesterday was trying to run a local loop test to the router at the remote (spoke) end. We were working iwth them in trying to put the remote router (which we manage) into a loopback mode.

How can we put the subinterface that is the other end fo the frame into loopback mode so that a local loop test can be done between us and AT&T (provider)?
I have a Windows 7 64 Bit machine, and I cannot find a way to disable the IPv6 Loopback. I looked at the article at How to disable IP version 6 or its specific components in Windows and shows how to set HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesTcpip6ParametersDisabledComponents to various values – but none of these seems to disable IPv6 Loopback. I attempted setting this value to 0xffffffff and 0x20 – restarting my computer after each change, and I still do not get this disabled.
I am using another software called Webdriver or Selenium that gives errors when debugging if IPv6 Loopback is not disabled. It seems to attempt to connect to [::1]:7055 and fails. Is there a way to force it to connect to 127.0.0.1.

i'm trying to setup a local DNS server to manage small office local-only domain names for our servers. i have the DNS working properly (resolving local machines and using the ISP dns if it can't). so i put the DNS server ip into the "Static DNS 1" field of the router settings. the other 2 static dns fields are empty.the problem is that the router is still using the ISP dns server as the primary and my local dns server as the secondary. i verify this in two places. first, if i go to the "status" tab, DNS 1 shows the ISP server while DNS 2 shows my local DNS server. secondly, if i connect to the wireless device with a linux-based machine, the /etc/resolv.conf file shows the nameserver ips in the same incorrect order.

I have a new 3560G to set up a small network for a remote site. I configured the vlan and an SVI as the gateway. The switch is also the DHCP server for the LAN. I configured Gi0/2 as L3 port, connecting to the nearest neighbor. My network runs EIGRP so i advertised the routes into the EIGRP process. The switch forms EIGRP neighbors and learns all routes in the enterprise network. The problems I'm having now are: 1. The switch learns all routes in my enterprise LAN and can ping devices in the enterprise LAN, but I can’t ping any interface on the switch from the enterprise LAN. 2.
View 5 Replies View RelatedI 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.
