Interesting though is that if I leave the home ASA with a private IP from the Uvese box, the tunnel forms and all works fine, but it is IPSEC over NAT-T. Thinking that the new box is a little different ( old one was a 2Wire 3800, this one is a Pace 5031NV) I went back to the old connection ( I have not canceled it yet).
ASA 9.5(2)204 and IOS 15.6 were used in my lab. This is similar to the topology used in Policy Based VPN, however there is a slight difference.The connection between the ASA’s and the ISP routers will use subinterfaces, in order to support routing over different interfaces. Note. The sample configuration connects a Cisco ASA device to an Azure route-based VPN gateway. The connection uses a custom IPsec/IKE policy with the UsePolicyBasedTrafficSelectors option, as described in this article. Remote VPN users connect to the Corp LAN using L2TP/IPSec VPN. A DHCP pool is reserved on the ASA for VPN users. We’ll also implement “split tunneling” so that regular Internet traffic is not sent through the tunnel. For simplicity, VPN user authentication is done locally on the ASA. You can configure RADIUS authentication to an AD. It is Re: Allow Cisco VPN Client through firewall? Generally the ASA will allow IPSEC traffic from inside to the outside. it;s when you want it to originate from outside and to connect to you - that's where it gets creative. Are you limiting outbound traffic at all??? Are you denying any ip/tcp/udp outbound? When inspect ipsec-pass-thru is configured, ASA inspects the control-plane of an IPsec session which is UDP 500 and if the peers negotiate to use ESP and not ESP-encapsulated-into-UDP-4500(case when a NAT device is in-between), it allows ESP traffic without you needing to create rules in your ACL's.

Sep 16, 2014 · Instead if you must tunnel directly through your ASA to the server, SSTP is a better option. Why not take advantage of the VPN capabilities on your ASA, which is purpose-built for encrypted VPN traffic with dedicated hardware based technology, which is an order of magnitude more efficient than software-only solutions.
Allowing Microsoft PPTP through Cisco ASA (PPTP Passthrough) The Microsoft Point to Point Tunneling Protocol (PPTP) is used to create a Virtual Private Network (VPN) between a PPTP client and server. It is used for remote access from roaming users to connect back to their corporate network over the Internet.
Group Policy The Cisco ASA supports VPN filters that let you filter decrypted traffic that exits a tunnel or pre-encrypted traffic before it enters a tunnel. You can use the VPN filter for both LAN-to-LAN (L2L) VPNs and remote access VPN. VPN filters use access-lists and you can apply them to: May 03, 2017 · By default, an ASA will encapsulate both IKEV2 negotiation and the IPSec encrypted packets in UDP 500. If you want to use NAT-T and encapsulate the IPSec packets in UDP 4500 then oort forward UDP 4500 on the NAT router and enable NAT-T on the each ASA: After successful login to the LDAP server, ASA sends a search query for the username provided by the VPN user. This search query is created based on the naming attribute provided in the configuration. Oct 15, 2015 · Their VPN of choice is PPTP and it comes pre-installed and is always on. I have no way to edit what this system uses for VPN. The idea was to encapsulate that network under the ASA Firewall within my network and make the PPTP port public while it is needed. I am sure there are easier ways to tackle this issue, but here are some of the requirements: Allowing Microsoft PPTP through Cisco ASA (PPTP Passthrough) The Microsoft Point to Point Tunneling Protocol (PPTP) is used to create a Virtual Private Network (VPN) between a PPTP client and server. It is used for remote access from roaming users to connect back to their corporate network over the Internet. The ASA will assign IP addresses to all remote users that connect with the anyconnect VPN client. We’ll configure a pool with IP addresses for this: ASA1(config)# ip local pool VPN_POOL 192.168.10.100-192.168.10.200 mask 255.255.255.0 Petes-ASA> enable Password: ***** Petes-ASA# configure terminal Petes-ASA(config)# management-access inside 2. Post version 8.3 you also need to have the route-lookup keyword on the end of the NAT statement (the one that stops the remote VPN subnet being NATTED ).
