View 9 Replies View RelatedI have a weird problem which I have already submitted a TAC ticket about. When users authenticate through AnyConnect into our HQ ASA 5510 they grab an address from 172.16.254.x. What we have been noticing intermittently is that when logged into our network through the client they are unable to access their resources at one of our remote offices which is connected over l2l to the HQ ASA. This problem just started randomly a week ago and we have been working with Cisco trying to create a solution.
My quick fix is logging into a device at the remote office which is trying to be accessed and pinging the gateway of the virtual subnet for AnyConnect users. When I ping 172.16.254.1 it goes through after a few dropped icmp packets and then the issue is resolved for about 8 hours or so.

we have two ASA 5510s one in 8.4(4) and one in 8.2(5) in a site-to-site VPN setup. All internal traffic is working smoothly.Site/Subnet A: 192.160.0.0 - local (8.4(4)) Site/Subnet B: 192.260.0.0 - remote (8.2(5)) VPN Users: 192.160.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible.
Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise.There are also some weird NAT rules that I am not happy with that were created after I upgraded Site A ASA to 8.4
Site A internal: 192.160.x.x External: 55.55.555.201(main)/202(mail)
Site B (over site-to-site) is 192.260.x.x External: 66.66.666.54(all)
I pretty much just have the basic NAT rules for VPN, Email, Internet and the site-to-site.What do I need to add for the VPN to be able to access the site-to-site network?
Here is my NAT config:
nat (inside,Outside) source static DOMAIN_LOCAL DOMAIN_LOCAL destination static VPN_Network VPN_Network no-proxy-arp route-lookup

I am configuring IPSec Remote Access VPN on a ASA 5505. There are one external interface and one internal interface configured on the device. Internal interface connected to subnet 192.168.1.0/24.en VPN client get connected, I would like to assign the IP from some subnet(for example 192.168.2.0/24) other than the current internel subnet (192.168.1.0/24), but the VPN client can still access to 192.168.1.0/24. Is there a way to do this?
View 2 Replies View Relatedbest way to migrate to a new pool for remote access DHCP address assignment. We are currently using a /24 pool, allowing us 253 IP Addresses... during the recent hurricane we hit 250 IP Addresses used, and had to start asking users to connect to our backup ASA VPN device in another country, not an ideal solution. I'd like to expand our current VPN subnet to a /23, however I do not have a free /24 subnet above (or below) our current /24 subnet.
I can certainly allocate a new /23 subnet, but I am looking for the best migration plan with minimal downtime (no downtime would be preferred). Can I just add the new pool range to the tunnel-group RAVPN general-attributes section alongside the current pool, or should I just remove the old pool, log off all existing remote access VPN users and have them log on again to start using the new pool?We are running ASA Version 8.2(1).

View 1 Replies View Relatedusing ACS 4.2 and I can't find a way to bind an incoming NAS port to a specifc IP Pool:
When a user connects the request to auth comes from 2 possible NAS ports randomly (this cannot change). Depending on which NAS makes the requests determines the IP range required, so I need 2 IP Pools. There is no way to say 'if request comes from NAS1 give IP from Pool1 and if request comes from NAS2 give IP from Pool2'
I have gone around and around with NAFs and NARs, but cannot do this.I can create 2 ACS groups with the specific NAS and specific IP pool within, but then I cannot have a single username bound to both groups.
I moved the auth to an AD group in the hope that I could bind that single AD group to the 2 ACS groups; and so have a single username, but no joy.

I was trying to set a DHCP pool with 127.16.0.0/16 with RV220W, however, RV220W UI can't save it. It displays "IP Address Range -"Step to reproduce: (it is 100% reproducible)
1. login into RV220W admin web
2. Create a VLAN, id 201
3. Go to "Multiple VLAN subnets", select the VLAN, click edit
4. Enter following info:
IP Address: 172.16.0.1
Subnet Mask: 255.255.0.0
DHCP Mode: DHCP Server
Domain Name: Cisco
Starting IP Address: 172.16.2.100
Ending IP Address: 172.16.10.254
Primary DNS Server: 172.16.0.1
Leave rest of settings with default value.
DNS proxy is enabled
5. Press Save button. The UI shows text "IP Address Range -".
Expected result: RV220W shall save the setting and make use of 172.16.0.0 subnet in IP pool. By the way, the error message "IP Address Range -" seems incompleteI tried same setting on netgear FVS318N (very similar settings to RV220W), it accepts 172.16.0.0/16 as DHCP IP pool and works.RV220W has great feature set meets my needs. Its UI is slow and sometime dashboard freezes, which I can live with comparing to features. But DHCP server IP pool can't be class B is huge limitation to me.
Can a layer 2 cisco 2950 switch be used as a dhcp server with it's own address pool.
View 3 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?
We have a scenario where the Cisco ASA 5505 will be one end of a site-to-site VPN. The same ASA 5505 also allows Client VPN connection. The question is around IP pooling. If I assign a pool of IP's (192.168.1.20 - 192.168.1.30) for Client VPN connections - do I need to be sure that those same IP's are not used on the other side of site-to-site VPN ?
There could be PC's/Servers running 192.168.1.0/24 on the other side of site-to-site VPN. Would this cause an address conflict ?
I have set this up on pre 8.3 code and 8.3 code as well. I have the following configured on the ASA, but it is not working and I am not seeing the ASA trying to NAT the VPN pool IP address that the client gets assigned.

One of our accounting administrators will be working in our server this weekend from his home remotely. He wanted to know if there was a way I could temporarily lock users from remoting in a few days to prevent them from messing up his work.The only way I could think of was disabling the accounts in Active Directory and then re-enabling them once he was done. Server is running Windows Server 2003 with the users remoting in via RDP. They all have accounts in Active Directory.
View 1 Replies View RelatedI have setup an SA520W and configured SSL-VPN for our small business. Everything seemed to go smoothly and I tested SSL VPN by logging in and playing around a bit which seemed to be fine. However, shortly after deployment I started getting complaints about it being much slower than our old VPN through the consumer grade router I just replaced. I investigated and tested with IE8 and Chrome on Windows XP 32-bit with several different machines, and in all instances it did seem very slow indeed. While looking around I noticed that the Task Manager under the Networking tab shows the SSL VPN connection as VirutalPassage at 64 Kbps. Going into Network Connections shows VirtualPassage under the Dial-up heading with device name Virtual Passage SSLDrv Adapter. Additional properties describe it as an ISDN channel. I have attached an image of the Task Manager pane.The router is running the latest firmware of 2.1.51. It is connected via a static IP that does not require a login, to our dedicated 5 Mbit / 5 Mbit ethernet over copper link to our ISP. We get great speeds and low latency through everything but SSL VPN connections. I haven't done anything fancy so the router certificate is the factory default. Currently we are using the existing 2 SSL VPN licenses that come with the router until we need more access, at which point I want to upgrade to the 25 user bundle. However, I don't feel comfortable upgrading until I get this resolved, because 64kbps simply cannot work for us for a VPN solution.how to configure the SSL VPN to not limit at 64kbps? My engineers are making fun of me for bringing us back to dialup, and I have to agree with them!

I have a problem on a Cisco ASA5520 version 8.2(5). A customer has set up a syslog to keep tracks of tcp sessions made by vpn users. On the syslog we filter %ASA-6-302013 and %ASA-6-302014 log messages, respectively: Built inbound TCP connection and Teardown TCP connection. When the connection is made by a vpn user, at the end of the log line you see the vpn username which should be the same in both the messages for the same connection. I have verified that when a user, let's say UserA, disconnects from the vpn, their tcp sessions are not properly closed; if another user, let's say UserB, establish a VPN immeditaely after and gets the same IP address previously assigned to UserA, the log sessions are recored with UserA in the %ASA-6-302013 message and UserB in the %ASA-6-302014 message. I presume this is due to the fact the tcp sessions are not tore down when the first user disconnects and it looks like a bug to me but I didn't find it referenced anywhere. Is there a way to have all tcp session tore down when a user disconnects the VPN connection?

The licensing seems rather complicated, therefore this is my question:
- What VPN solution do you recommend for our users and contractors? it is my understanding the CISCO VPN client does not work with ASA 5500 series devices
- Is there a license needed to deploy VPN solutions for our remote users(employees/contractors)?
