I'm setting up a bunch of VPN tunnels for a customer of mine. Because we want the ability to fail over tunnels manually and to change IP addresses in the future without having to reconfigure both sides we want to build the VPN tunnels to hostnames instead of IP addresses.[CODE]

View 1 Replies View RelatedI've just installed a 2504, upgraded the firmware so that 3602i ap's can attach. As a test I left the network open and am running dhcp from the 3560 switch. Why am I unable to ping or connect to a device by name within the same subnet on the "wired" network? There's no DNS server.

We have a brand new Linksys X3000, with the latest firmware installed. It does not recognise the hostnames of devices on our network. We have added a few hostnames, using 'manually add client'. My first question is why would it not recognise hostnames (a variety of devices, e.g. phones, apple time machine, linux PCs)?
The next problem is that that we are successfully able to ping IP addresses, but when we ping hostnames, results are inconsistent. e.g. currently I have my laptop and a time machine connected by wire directly to the router. I can ping the time machine by IP. The first time I ping by hostname, it works, but immediately after that I ping again and it says 'unknown host'. Why would it suddently forget about a device it is clearly connected to? Have we got some sort of default security setting I don't know about?
we want to replace our 1242 AP's with the 1602 model and so far everything works like a charm. We have just noticed, that most of the clients which are connected on the 5GHz N radio, the web interface of the AP1602 shows his own host name instead of the clients host name.
For example:
Radio0-802.11N2.4GHz
SSID INTERN :
[code].....
The Host name of the 1602 is "AP-LABOR", so why it shows the own host name for the Dell E6420 Notebooks on the 5GHz radio and on some "NONE"?
I am having an issue where occasionally the Sidewinder starts to see my internal RFC 1918 address instead of the configured external address of my firewall. This is for peering between the two. The error they see on the Sidewinder is:So instead of seeing the external peer address he sees a 10.220.3.18 address. We are not sure what triggers this becuase normally he see's my 63.117.98.222 address.
View 5 Replies View RelatedI have an old ASA 5505, and I'm having some trouble with Nat Hairpinning. I've done this with other firewalls before and I am having no luck now. I have an internal address that I wish to forward from an external address- so if someone goes to 123.456.789.012:3456 then it will forward to 192.168.1.244:92 (All numbers are arbitrary here- only for illustration). I have and Access Rule and NAT and PAT set up so that I can get in if I originate from outside the LAN. What I am trying to do is to have this work from inside the LAN as well- so that if I am at my desk, and I connect a device and type in 123.456.789.012:3456, it will deliver the content at 192.168.1.244:92. The problem I am having is that it just isn't working, and I cannot figure out why- When I started here, there was an address configured to work this way, and it still works- I just cannot find what is different between what I am doing and what the person who configured it did.

View 6 Replies View RelatedI recently configured and installed a 1941ISR for a customer. The customer purchased a 25-User SSLVPN license with the router, and I configured it for remote SSLVPN access. This is working nicely except for one issue: when users initiate an SSLVPN connection request by browsing to the assigned webvpn gateway IP, they get the "There is a problem with this website's security certificate" browser message. They are in the process of working with their DNS hosting provider to get a DNS entry assigned to the IP address so the users won't have to specify an IP address in the URL address box, but they will continue to get the certificate error until/unless I can figure out how to resolve the issue.
I've tried the following "How to make IE8 trust a self-signed certificate in 20 irritating steps" that I found via another forum link but with no luck:
1.Browse to the site whose certificate you want to trust.
2.When told "There is a problem with this website's security certificate.", choose "Continue to this website (not recommended)."
3.Select Tools->Internet Options.
4.Select Security->Trusted sites->Sites.
5.Confirm the URL matches, and click "Add" then "Close".
6.Close the "Internet Options" dialog box with either "OK" or "Cancel".
7.Refresh the current page.
8.When told "There is a problem with this website's security certificate.", choose "Continue to this website (not recommended)."
9.Click on "Certificate Error" at the right of the address bar and select "View certificates".
10.Click on "Install Certificate...", then in the wizard, click "Next".
11.On the next page select "Place all certificates in the following store".
12.Click "Browse", select "Trusted Root Certification Authorities", and click "OK".
13.Back in the wizard, click "Next", the "Finish".
14.If you get a "Security Warning" message box, click "Yes".
15.Dismiss the message box with "OK".
16.Select Tools->Internet Options.
17.Select Security->Trusted sites->Sites.
18.Select the URL you just added, click "Remove", then "Close".
19.Now shut down all running instances of IE, and start up IE again.
20.The site's certificate should now be trusted.
I followed all 20 irritating steps to the letter, but am still getting the security certificate nat.Now when I “Continue to this website (not recommended)” and click on "Certificate Error" at the right of the address bar, the certificate error windows says “Mismatched Address”.Is there a way that I can get this fixed without resorting to a 3rd party CA?

I recently switched routers to the DIR-615 and I'm trying to troubleshoot why one of our laptops keeps losing the IP address and gets a self-assigned IP address. I see the following messages in the log, I am wondering if the reason codes are listed and explained somewhere? I tried searching the manual but could not find any information.
View 9 Replies View RelatedWe have an ADSL connection and use a D-Link DSL-320B modem. We have a D-Link DIR-120 router connected to this modem. This has worked perfectly fine up until today when we disconnected the router and connected a computer (call it A) directly to the modem because it was getting an unusable connection through the router for some reason. We later also performed a factory reset on the DIR-120 router.
Unfortunately, after the above steps the router did not receive any IP address (through DHCP) from the ADSL connection anymore. During my attempts to debug this I noticed that my laptop (call it B) didn't get any IP address either (when connected directly to the modem). I noticed the following syslog entries repeating over and over while trying to connect: [code]
At this point computer A could still get a connection just fine tho (when connected directly to the modem).
I then tried to change the MAC address of the router to an arbitrary one (a copy of computer B's MAC address but with the last digit increased by one). The router still did not get assigned any IP address. Finally I tried making the router clone the MAC address of a third computer (call it C). C has never been connected directly to the modem. Doing this worked. After cloning the MAC address of computer C the router is immediately assigned an IP address and the internet connection works as it did prior to all this.
Now, my question is, why would computer B and the original MAC address of the router not be able to get an IP address while two other computers worked just fine? Why would changing to an arbitrary MAC address not work while cloning the MAC address of another computer did? Could the router's MAC address have been blocked by the ISP for some reason (and what could cause this)?
but my situation seems more like a blacklisting of some MAC addresses rather then allowing just a single MAC address.
I need to change the ip address on my router same ip address as myDlink router?

Some Routers support DHCP spoofing (zyxel / speedtouch).With DHCP spoofing (or half bridge) you can directly spoof you'r public IP address to the firewall. Firewall gets public IP address directly from modem. Benefit of this (no waste of an extra IP address). Modem has no IP address. It has to be possible with an 8xx series router I heard, but I cannot find how.I guess it can be done with a bridgegroup with the dialer and VLAN 1 in it (no ip addresses given).I tried but without any result.

I have FE4 (The WAN port) set to get an ip address via DHCP, but when I do a test connection from CCP I get this error: Checking interface IP address…failed.No Ip Address for the interface has been obtained. The interface is configured to obtain an ip address through dhcp. The remote end may not be configured with a dhcp server or the dhcp pool may be empty.
Please contact your ISP or WAN administrator and check if the server has been configured to lease ip addresses to the client’s connection through DHCP.
