I managed to setup a 1721 router as a vpn server connecting to it using a cisco vpn client however altough I am obtaining an ip address as defined in the dhcp pool I am unable to communicate with both the remote network and also I have no internet as soon as I connect.

Monday, I had a cisco 1750 router in place suddenly stop communicating to a Larscom ISP owned unit. Since then I have sent two replacement 1721 routers with WIC-1ENET cards. I have used the original straight thru cable to connect the 10baset port on the Larscom to my E0 on the WIC-1ENET. No link lights on either. I have also tried a known working straight thru cable and a crossover cable. No link lights.
I can take a crossover cable from a pc and ping the E0 port without issue. The ISP is telling me it is an issue with my equipment.
Trying to work out if I can setup a VLAN interface on a 1721 router.The only interfaces that are listed are the Ethernet (W1-ENET) and the Fast Ethernet interface.I'm still super new to all of this and learn how to change IOS via rommon and TFTP after realizing I had an IOS too large for the memory?

I thought I had read somewhere that tunnels were not supported on the 1700s but wanted to make sure. If they are I would like to know if they are supported in the above ios.
My internet is T1 by Verizon. My mom's company Siemens pays for our internet because she works from home as medical tech support on the phone. Okay so the T1 had to be laid out to our house underground I think because where we live, other brands of internet aren't available. The T1 goes from the box outside into our basement and hooks up to a Cisco 1721 modem. From the 1721 the internet goes out to a wireless router that is sitting right next to it. This wireless router is a Linksys WRT160N V2. We have several cables coming out of the WRT160N V2 to go to the first floor for hardwired connections, but one cable goes to the attic and connects to a second wireless router. The second wireless router is a Linksys E2000. We have several cables coming out of the E2000 that go to the 2nd floor to serve as hardwired connections.Okay so let me explain where things went wrong.
After a storm our power went out. Eventually the power came back on, but every now and then our internet would shut off for like half a day then turn right back on, so our internet was getting really really spotty. The [b]AL[/b] light on the Cisco 1721 would come on every time the internet went out. It was so bad that my mom had to get an aircard from verizon to get internet. So after two weeks of spotty service and arguing with verizon trying to get them to come fix the problem, they said try resetting your wireless routers because they might have "bad data" in the lines causing spotty connection. So we reset the wireless routers by holding down the reset buttons on the back. Well.. this reset all of the settings for the routers which Cisco facilitated set up, and now our wireless routers are out of warranty date so they can't set the wireless routers back up. However, we have copies of the online wireless router set up page, so we thought maybe we could just set them up ourselves.Well the problem is... We don't know how to connect to the wireless setup pages.. I read something on the internet about setting up wireless networks and to type 192.168.1.1 into our browser(Mozilla Firefox) and that would bring us to the wireless setup page. But the page does NOT ever come up.
Another way to find the IP address of our wireless routers would be to try going to the cmd and typing in ipconfig and using the Default Gateway IP address for the browser to connect to the setup page but that doesn't work out either.... Right now I unhooked the Linksys WRT160N V2 and hardlined the Cisco 1721 to the Linksys E2000 to a PC on the second floor because I figured it wouldn't work out if we had two wireless routers running at the same time. Currently the browser is taking me no where at all. It just says "Connecting..." but nothing is loading up at all.I tried hardlining from the Cisco 1721 to my mom's laptop, which is her work computer, and I got no response at all. I figured it might just be her work computer that was messing up and not allowing her to hardline into the 1721 so I tried hardlining the Cisco 1721 straight to the PC desktop on the second floor(we have no other laptops other than my mom's work laptop) and nothing went through. Then my dad says the Cisco 1721 has been configured so it doesn't direct connect, meaning that it has to go through a wireless router.
I have a 1721 router in my home & I want to setup it for firewall/ vpn. Is it recommended to purchase a WIC-1ADSL? What module is recommended for VPN? Is it possible to setup VPN using DSL / Dynamic Ip connection ?I want to explore on Cisco security & I get this advice from a supplier.

I have the public IPs.
About my internet setup, I receive internet from my ISP via the LAN cable. The IP is static, provided by the ISP. To use the internet, I have to login to their server using a username and password.Earlier, I did not have a router. So, to see if the ISP server was up, I could just ping the IP of the ISP server from my computer using the command prompt, and it would show whether it was up.However, since I got a router, I find that I cannot ping the ISP server from the computer directly as before. To ping the ISP server, I have to open the router administration page using the browser, then use its diagnostics feature to ping the ISP server. It shows only a few pings, and is not like the continuous ping that can be seen when you run ping from the command prompt. So, it's difficult to see the pings, and also diagnose. Also, sometimes the router pages do not open and get stuck, even after being refreshed.Is there any way, or any setting, by which I can ping the ISP server from the command prompt on the computer? Do I have to make changes in firewall settings of computer, or any settings in the router?Why can't I ping the ISP server directly from the computer?I am using Windows 8. The firewall of Windows 8 is on, and the hardware firewall on the router is off.

I have a 1721 router with 3 equal routes to 0.0.0.0, using CEF for load balancing with universal load balancing algorithm. It doesn`t NAT, just routing. I wonder which is the maximum capacity of the router, since it should support up to 40000 connections to different destination IP. Is the limit set by the router resources (CPU, memory, ...) or a maximum limit of entries in the table FIB / RIB?
View 7 Replies View RelatedI have a linksys router WRT54G connected to a modem supplied to me by Time Warner Cable. Just last night, for some reason my internet stopped working. After calling Time Warner Cable internet support, I found out that the modem is working. If I connect my laptop (Dell model which is running on Windows 7) directly via cable to the modem, I can connect to the internet. BUT if i connect my modem to the router, and then connect my laptop via cable or wireless to the router, I can't connect to the internet. When I open up my network window on the computer, I see that my laptop is connected to the router and the router is connected to the internet but I can't connect to the internet. I tried calling linksys customer service and my insurance ran out so yea ... On the laptop, i ran a troubleshooting program and it gave me an error stating that it failed to connect to the DNS server and I should contact the internet provider. Time Warner Cable told me that if connected to the modem directly, I could access the internet indicating that there's an error in the router.

I've been messing around with this for several weeks to no avail. I've never had a problem establishing a VPN connection within my LAN. I've tried several workarounds, learning things in the processs, but to no avail.I've set up a VPN connection with Windows 7. The RRAS server is at home and I'm attempting to access from school (or the internet anywhere).I have no problem establishing the VPN connection (that I can see). Port 1723 is forwarded for both UDP and TCP to a static LAN address (198.162.1.124) in the E4200. PPTP pass-through is enabled (as well as the other two options).I can't see anything on the server after connecting. I'm using a DDNS. It works just fine INSIDE the LAN; I've even mapped a network drive to "S:". Accessing ANYTHING outside of the LAN over a VPN, however, isn't working. [code]
View 9 Replies View RelatedI would like to setup RDP on my cisco router so I can access my server from outside my network. I also have a router from my ISP that has DHCP for my external IP address and DHCP for my internal as well.
View 3 Replies View RelatedLong time since I have had to configure a router and have a small project
Here is what I have in a simple diagram:
PC(static IP)--to--Switch--to--(Ethernet0 int, WIC0)1721 router(FastEthernet0 int, built-in)--to--Switch--to--PC(DHCP)
I need static IP PC to be able to ping the DHCP client. Static IP units 10.1.1.x/16, DHCP clients 10.1.3.x/16.
I have found these overlap and thus give errors and will even shutdown the interface if I enable certain things like routing or bridging.
So I gather I need to change one interface IP range, which would be the DHCP side, I need to stay 10.1.1.x/16 for static side.
enable dot1q encapsulation on two ethernet ports on a 1721 router. I am able to configure it on the built in fastethernet port, but not on any interface provided by a WIC-1ENET or a WIC-4ESW. I have an application that requires two physical ethernet ports that support dot1q encapsulation.
View 4 Replies View Relatedi've been using a VPN to connect to my home network from elsewhere for a few months. It's set up as follows:
PPTP
Maximum Strength Encryption
EAP-MSCHAP-v2 Authentication
Now I find out that MSCHAPv2 authentication has been broken and is no longer considered secure (even by Microsoft), so I want to change the protocol I'm using to make it secure.
However, I've spent 3 hours now researching this and I cannot for the life of me figure out how to use a better protocol on my Windows Server 2012 home server. I've tried setting up PEAP authentication (still PPTP) a la Microsoft's recommendation document, but it requires a certificate. I've created a self-signed certificate but it seems I can't issue certificates (via this method) without being a member of a domain, so I'm stuck. I can't even get started with L2TP since I can't find the option for it.
My question is this: Is there a way to setup a secure VPN server using Windows Server 2012 without a domain? If so, how do I do this?

I am working on a backup system for my WAN. Verizon quoted the HWIC-3G-CDMA-V to work with my Cisco 1721 router. I have a bunch on these routers on a shelf and thought I would use them for the 3G network. Looking at the Cisco web site it does not list the 1721 as being able to work with this HWIC. I thought it might not be listed as the 1700 series are End of life. Whether it will work?

The problem I have is that all of the devices want to use port 80 to generate the web page. Individually, I can get the boxes to work, but when I try to put it all together everything seems to fall apart. I've got to the DVR set to External port 80, Internal Port 80 IP address 192.168.1.254. The web page server box I try to set to External port 8001, Internal port 80, IP address 192.168.1.200, when I try to save this setting I get the error message Internet IP address and LAN IP address are in the same subnet. If I change the web page server settings to External port 8001, Internal port 8001, IP address 192.168.1.200, it will save the settings, but it won't work that way because it won't actually generate a web page when I try to access that port.The error message doesn't seem to make since as all I'm changing is the port number, not the IP address or subnet mask.
