from 7.2 to 8.4 code. After the upgrade was finished, I noticed that internet access for my VPN users coming in over a full-tunnel connection was failing. The debugging I did led me to seeing TCP connections being torn down due to "no valid adjacency." This was caused by a NAT rule sourcing from any destined for my VPN subnet. Based on looking at the configuration, I believe https://supportforums.cisco.com/discussion/11967411/access-issues-no-valid-adjacency the NAT rule was used to NAT exempt internal network traffic to the VPN users. In the examples below, these are the object groups: object-group network Inside_LAN network-object 10.1.1.0 255.255.255.0 object-group network VPN_Clients network-object 10.1.250.0 255.255.255.0 The NAT rule causing the problem was: nat (inside,any) source static any any destination static VPN_Clients VPN_Clients http://www.jjohnstonit.com/wp/2011/11/asa-8-4-no-valid-adjacenc/ I fixed the issue by setting up a more restricted NAT rule: nat (inside,any) source static Inside_LAN Inside_LAN destination static VPN_Clients VPN_Clients asa 8.4nat Post navigation Previous PostMerge private key with certificate using OpenSSLNext PostWindows 2003 RDP Desktop session or parts of Desktop session is black Leave a Reply Cancel reply Your email address will not be published.Comment Name Email Website VMware Networking Microsoft Article Categories General (1) Microsoft (9) Exchange 2007 (1) Exchange 2010 (2) Windows 7 (3) Windows Server 2003 (3) Windows Server 2008 R2 (4) Windows XP (1) Networking (5) Cisco (5) ASA (1) VMware (2) vSphere 5 (2) Recently Archived January 2013(1) August 2012(1) July 2012(2) May 2012(3) April 2012(1) February 2012(2) December 2011(2) November 2011(5) TagsIOS sslv2 windows registry offline files certificate nps sfp relay rdp dhcp reservation vmware wireless password management catalyst ldap sso mks spooler openssl iis 6 asa win2k3 peap asa 8.4 vpn err-disabled vsphere nat printers exchange 2010
before I was hired to my current position, a new IP phone system was installed on the network. The phones were given a new IP range/ For example: Data https://community.spiceworks.com/topic/519424-cisco-asa-new-ip-range traffic - 10.0.0.0/16 Phones 10.1.0.0/16 I am forced to use the "computer" port on http://serverfault.com/questions/447896/exposing-the-anyconnect-https-service-to-outside-network some of the phones due building constraints. The phones can access internal network resources just fine, but when they go out to the internet through the ASA I get the following message: Teardown TCP connection 55072458 for outside:74.125.196.84/443 to inside:10.1.0.24/52914 duration 0:00:00 bytes 0 No valid adjacency I didn't setup the firewall either- and i'm assuming no valid it is an issue with the NAT, but I really don't know where to start the troubleshooting.

That will be your best bet if there is. If not then you may want to consider setting this up on your own terms. I wouldn't foresee it taking to long and this way you have peace of mind for the future. 0 Mace OP NetworkNerd Jun 17, 2014 at 2:35 UTC Are you familiar with how to login to ASDM and look at NAT rules? 1 Sonora OP Todd9945 Jun 17, 2014 at 4:08 UTC Yes, I can log into the ASDM and look at the NAT rules, but not quite sure what i'm looking for 0 Thai Pepper OP Dave Rossi Jun 17, 2014 at 4:13 UTC What is the IP and subnet of the internal interface of the ASA? 0 Sonora OP Todd9945 Jun 17, 2014 at 4:30 UTC inside IP 10.255.255.254 255.255.255.248 subnet 0 Sonora OP Todd9945 Jun 17, 2014 at 4:38 UTC 10.0.0.0/13 (data networks)- appears to have NAT working properly.
