Is it possible to configure an IPSEC GRE tunnel with RIP on an SRP527w? I see RIP, GRE & IPSEC are all possible.. But I'm not sure about them all together securing the GRE tunnel??
I basically want to do this with the SRW routers not native IOS. Single head end hub & spoke.
I installed a 1941 router with an encrypted GRE tunnel yesterday. The router has ipbasek9 and securiyk9 licensed. Initially the router was running the image c1900-universalk9-mz.SPA.150-1.M5.bin and was working fine. The tunnel was up and passing traffic. I then upgraded the IOS to c1900- universal k9-mz.SPA.151-2.T2.bin and when I reloaded the router the tunnel was stuck in a reset/down state. I tried doing shut/no shut on the interface and reloading the router again, no change. Being under some time pressure to get the device back into production I rolled back to the previous IOS image and the tunnel worked fine again. Is there a known bug that causes this behavior? I have searched cisco.com but have not found one. [code]

Currently I have a different setup:Both routers have the DHCP server enabled and I connect R2's WAN port to R1 LAN. Therefore I have 2 subnets. Now my special requirement is that R2 is a DD-WRT router, which establishes a VPN connection to StrongVPN, so that all internet traffic via R2 is encrypted and goes through the StrongVPN server. Now my question:If I change my router setup to the same subnet, meaning R2 connects LAN to R1 LAN and I disable DHCP server on R2, will R2 still be able to establish the VPN connection?

Problem is when I try to connect to my wireless network, it comes up as being security protected...and it isn't...and never has been. I have other computers connecting just fine, but I can't seem to figure this one out. I don't have a key to enter as there isn't one! I installed a USB wireless adapter, and it works fine, but I don't want to use the adapter on the laptop.

View 7 Replies View RelatedI am actualy trying to make a remote access VPN between a ISR1921 and Windows 7 pro. I already managed to put a PPTP VPN with an authentication against our LDAP databse via radius. But our password are in SHA1 in our LDAP, so I had to let the password unencrypted on the network using pap and this is bad.If I don't use pap, it simply doesn't work since all the other method need unencrypted password for the challenge authentication.Does that mean that every remote access VPN keep our password unencrypted ? Maybe use EAP (but I can't find a howto or good documentation about it)? Can I add a certificate or something?
View 1 Replies View RelatedI've configured an ASA5505 to be Lan to Lan VPN tunnel endpoint, peering with a linux box. The ASA is full licensed so that side isn't an issue.PROBLEM:When the tunnel is initialised from the linux box everything comes up okay except the ASA isn't encapsulation any packets. It is decrypted the packets received from the Linux box okay but no return traffic is being encrypted.When the tunnel is initialised from the ASA, nothing happens.After some troubleshooting I've found that the ACL defining interesting traffic nor the ACL defining NO_NAT aren't being hit at all.
ACL for NO_NAT:
access-list NO_NAT line 1 remark ACL USED TO DEFINE WHAT TRAFFIC NOT TO NAT OVER THE VPN
access-list NO_NAT line 2 extended permit ip host PAMS_SERVER object-group LINUX-BOXES 0xc736d5fb
access-list NO_NAT line 2 extended permit ip host PAMS_SERVER 10.11.228.0 255.255.255.0 (hitcnt=0)
[code]....
I've checked with the administrator of the linux box and the definition for interesting traffic is exactly the same (except in reverse as should be the case).The firewall is doing other things like NATs and such like too but those NATs have nothing to do with this VPN. The setup is a LAN to LAN connection with no natting in between.The main parts of the config are attached, i've deleted things that should have a bearing on this however if you think it necessary i can sanitise the config and re-post. I think it will be working fine as long as the traffic hits those ACLs, however they're not and I'm unsure why.At this time i'm not seeing anything at all when doing an debug cry ipsec or debug cry isa. The ACL's aren't being hit so i'm guessing it's not even trying to form the VPN as it can't see any traffic that constitutes being 'interesting'.
I have
MLS : C6509-E
SUP : VS-S720-10G
PFC : VS-F6K-PFC3CXL
I'm trying to find out what is its limitation for encrypted traffic via SVTI there .
I don't have a SPA for the ip sec .
How WEP cracking works. I have a much better understanding now but it seems whatever programs I download and however close I get I always hit a wall somewhere. I am using windows 7 64 bit and my network adapters/cards are Broadcom 802.11n Network Adapter and Broadcom Netlink(TM) Gigabit Ethernet. I am not sure if these are adequate. I was using Commlink and aircrack but not sure if they are compatible and which versions i should have installed. I got as far as the collecting packets stage but the packets that appeared said ENCRYPT which was not correct and then my computer went to blue screen adn shut down and I had to system restore.
View 1 Replies View RelatedThe only way we can use our Motorola router is unencrypted. I have gone into the router numerous times and reset it, unplugged it, retyped the WEP key, tried to shift to WPA and nothing works. None of three computers in the house will connect unless all encryption is off. We live in a good neighborhood on a cul de sac, don't get a lot of traffic through here, and know the immediate neighbors, but nothing is stopping a stranger with a laptop from sitting on the street and using our wifi. I've talked to the Comcast tech. The trouble just seems to be our boxes won't get past the WEP encryption stage.

For username and password, ACS will export the data from Oracle database (production DB). The problem that we are facing right now is password that store in oracle database is in encrypted format. Base feedback from our database administrator, the encryption is done by oracle - application layer and cannot be decrypt back. In Oracle they call it "Oracle Stored Procedures"
My questions :
1- Can Cisco Secure ACS 4.2 work with Oracle 10G or 11G?
2- Is there any option to tackle the encrypted password? Can ACS handle the "Oracle Stored Procedures" function?
are the connections between the ACS and external identity stores encrypted?I know that when setting up LDAP identity store there is the option to specify SSL conection. Are the other connections encrypted by default, or is the data sent between the ACS and AD, for example, sent in the clear?

View 6 Replies View RelatedThis is a 5-year-oldish Gateway MX-6124 laptop running under Win XP 2002, SP3. I'm using SureWest DSL, with an ISP-supplied ComTrend NexusLink 5631 Modem/Router. The router is set up as a Secure Network, using WPA encryption. The laptop wireless operation light toggles off/on correctly using Fn-F2 control keys.I can connect to an open or non-secured wireless router, & have verified that at my church, at the Public Library, and at Starbucks. However, I cannot successfully connect to a passworded secured wireless source. I tried to use a secured network connection at my church yesterday, and could not connect. It "tries & tries" and eventually gives up and displays a cannot-connect type of message.
The laptop has worked correctly for several years on my home wireless network. It only stopped working about 3 or 4 weeks ago. I cannot recall changing anything in setup; I probably did it accidentally.I've spent about 2 hours in a couple of sessions with SureWest tech support. They diagnosed router setup using direct connect to the router, plus they talked me through several attempts at configuring the wireless config setup on the laptop. Everything I reported to them on the config settings appeared to be just fine. They also deduced that the wireless config on the desktop & router was correct.SureWest techs finally concluded that something was wrong with my laptop software config or the hardware, disabling it from making a encrypted connection. That sounds right to me, now having witnessed the secured connection failure described above, at my church wireless site.
I've looked at all the refs & things I can think of, plus followed step-by-step directions a couple of times with the SureWest techs. They rightfully pointed out that they could not make a tech support repair call on what did not appear to be a SureWest-related problem.I can easily make screenshots of any config screens needed on the laptop & upload to this forum.
The design is typical Cisco unified wireless solution. In such a implementation, is the traffic from the guest user who has successfully authenticated via WEB-AUTH encrypted? If so, what is the standard used, AES128 or TKIP?

All worked well however there is one site running really strange. The tunnel between 1900 is up for a while and down. Reboot router seems to be the only fix. But tunnel to ASA does not seem to be down at all.
The issue happened again today, we rebooted the router on site but tunnel still not up. DEBUG shows: deleting SA reason "Death by retransmission P1 "
I can see alot of Apr 24 19:57:55.271: ISAKMP:(0): retransmitting phase 1 MM_NO_STATE...
To me it seems like the IDE packet sent but never got reply and timed out. I did also check on the other end, the HQ. All other tunnels are still running fine on that router, just this remote site. Plus I got the similiar output when debugging on HQ router.
One thing do notice though, there was no match on both router for the ACL to match/permit ESP traffic... I asked on-site staff to reboot the modem used in remote site.
I have establlished VPN tunnle between 2 locations

Here is the situation: A CISCO871 router is configured to establish an IP SEC tunnel with a CISCO ASA5520. The configuration is OK about that. I wish to configure the same CISCO871 in order to establish a LAN-to-LAN IP sec Tunnel with another CISCO871 at the same time in order to reach private network. So, I have followed the Cisco procedure Document ID: 71462 "LAN-to-LAN IP sec Tunnel Between Two Routers Configuration Example"; it works, I can reach the peer private network BUT ONLY when the IP SEC tunnel with ASA is not established.
It seems to be a routing problem...I don't find how to configure to make both tunnels up and functional at the same time.
I have a new Inspiron 7520 and having issues with connecting to my secure network. In trying to troubleshoot the issue, I've discovered I can connect to my network when the connection is unsecured. When its encrypted, my connection is only limited (no IP address assign). I've also downloaded and installed the latest drivers with no resolution to my issue.
