It was suggested that I need to apply a TCP Map to interfaces on a Cisco ASA to stop TCP options being stripped (which prevent the correct operation of our VPN system). &nbsp;I have some instructions for doing this via ASDM, but we only have access to configure the ASA via CLI. &nbsp;Can someone walk me through this on the CLI (I'm assuming it's easy if you know how)?<br />
<br />
1-Build a TCP-Map with the following settings:<br />
Queue limit: 0<br />
Timeout: 4<br />
Reserved bits: Allow only<br />
Drop packets which have past-window sequnence: Yes<br />
Drop SYNACK packets with data: Yes<br />
Drop packets with invalid ACK: yes<br />
Range to Add:<br />
Lower: 6, Upper: 7<br />
Lower: 9, Upper: 255<br />
Action: Allow<br />
<br />
2-Apply TCP-Map to the ASA interfaces via a new service policy with the following config:<br />
Traffic clasification: Any<br />
Connection settings: Use TCP-Map (tick), an select the new TCP-Map, and then apply changes via ASDM.<br />
<br />
Can someone walk me through this on the CLI please?<br />
<br />
Thanks<br />

Cisco ASA - Create TCP Map using CLI

Networking hardware includes the physical devices facilitating the use of a computer network. Typically, networking hardware includes gateways, routers, network bridges, modems, wireless access points, networking cables, line drivers, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, ISDN terminal adapters and other related hardware.

Networking Hardware-Other

Network security consists of the policies adopted to prevent and monitor authorized access, misuse, modification, or denial of a computer network and network-accessible resources. Network security involves the authorization of access to data in a network, and covers a variety of computer networks; conducting transactions and communications among businesses, government agencies and individuals. Networks can be private, such as within a company, and others which might be open to public access.

Network Security

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.
