Is it possible to set up a vpn tunnel on a 1721 router that uses the following ios:
c1700-y7-mz.124-13b.bin
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.
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?

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.
We have VTI tunnels between Cisco (3825 and 878) and Juniper (SRX3600).Sometimes tunnel is going down and I should manualy shutdown and no shutdown tunnel interface to bring it up.This is logs from Cisco:%%crypto-4-recvd_pkt_inv_spi: decaps: rec'd ipsec packet has invalid spi for destaddr=X.Y.100.200, prot=50, spi=0xc5d07a33(3318774323), srcaddr=X.Y.100.100 ,%%crypto-4-ikmp_no_sa: ike message from X.Y.100.100 has no sa and is not an initialization offer.
View 3 Replies View RelatedVPN tunnel between ASA 5520 ver 8.0(4) and a remote Juniper firewall keep tearing down during Phase 1 rekeying. After the rekeying process fails, manually pinging one of the remote hosts that are proteced behind the Juniper firewall,initates the tunnel renegoation and rebuilds the tunnel successfully.
When the tunnel is down, sh crypto isakmp sa shows no active SA for the remote peer. That indicates the PHASE 1 negotation had indeed failed.When the tunnel is working, sh crypto isakmp sa indicates an IKE role of Responder - always.Clearly that also means Phase 1 negotation works only one way, i.e. negotation initated by the remote Juniper unit only.
Interestingly, the Syslog server logged the following SNMP trap messages at the time rekeying Phase1.Note, Line#2 and #7 and wrapped to the next line for easy of reading.
Line#1: IP = Remote-Peer-IP-#, Starting phase 1 rekey
Line#2: IP = Remote-Peer-IP-#, IKE Initiator: Rekeying Phase 1, Intf outside,
IKE Peer Remote-Peer-IP-# local Proxy Address N/A, remote Proxy Address N/A, Crypto map (N/A)
Line#3: IP = Remote-Peer-IP-#, constructing ISAKMP SA payload
[code]...
As I understand from the above syslog trap, the Responder ( the ASA unit this time) started Phase 1 rekey (Line #1). It prepare a message to be sent to IKE Initiator, that it is about to start rekeying Phase 1 (Line #2). Down on the next line, it indicated that the local Proxy, remote Proxy and Crypto map as N/A ( not avaiable).Why would the ASA unit send N/A message as shown in Line#2, is that normal?
I'm having an issue bringing a L2L tunnels up between my ASA 5510 and an ISPs Netscreens. I can establish the tunnels from my side by initiating traffic to the far end. The tunnels come up and stay up as long as there is traffic. Once the tunnels drop, they will not re-establish with inbound traffic. The only way to re-establish the tunnel is to send traffic outbound from our network. My ASAs are on ASA Version 7.0(8) in active/standby. [code]
View 2 Replies View RelatedI have a ASA 5520 with a functional IPSEC VPN using the Cisco VPN client. This allows my remote users (Staff) using laptops to come in from anywhere on the Internet and tunnel in. Works great.Next, we need to stand up a VPN over a Juniper SSG5 so that when we have groups working outside of our network, they can tunnel back into our network. If they were going to be coming from a known, fixed IP, or even netblock, we'd probably use Route-based setup from a Juniper SSG5 into the ASA 5520. But they may very well be coming from any IP. I am thinking this leads us to Site-to-Site VPNs- it won't be Network Client access obviously, nor will it be Clientless (browser-based).

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 RelatedMonday, 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.
I am in the process of configuring two vpn tunnels on one interface of cisco router series 1721. Any link or document with more information?

I have cisco 1721 router so I installed an ethernet interface card so when I make show run I found that there is a fast ethernet 0 and ethernet 0 (which I installed) so i wand to make subinfaces of the etheernet 0 but I can't. I tried to make encapsulation dot.1q but it doesn't accept it.
Is Ethernet0 supported to generate subinterfaces?
Long 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.

For example i need 192.168.255.0 / 25 on my side and i need to plug in a laptop on the far end 2941 with the same network. I have built GRE tunnels before and i found a configuration online to brdige interfaces over a GRE tunnel.
when i get to adding the bridging to the configuration which i will show below i get an error. Please see below. Also when i try to add the same briding command on the GRE tunnel which is needed it doesnt show the bridging command as being available.

I just joined this company and they already ad a VPN to one of their partners that provides them access to some resources.

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 am using a bunch of Cisco 1721 routers for my T1 lines. We recently purchased Digi cell modems as a backup for the T1. On configuring vrrp to work on both devices I discovered that IOS 12.3(6c) does not support the "vrrp track" feature.

We have changed secret keys, tried 3DES, AES, and AES256 encryptions with SHA-1. All the internal IP settings are correct :IE 192.168.1.1/24 or 192.168.1.1 255.255.255.0,External IP's are right, only oddball thing here is one of the external IP's is assigned by DHCP and is a /22 although the previous tunnel worked with the same ISP.
