Internet Protocol Security (IPsec) policies specify a set of encryption and authentication settings for an Internet Key Exchange (IKE).
In this video we will learn about How To Configure L2TP VPN in Sophos XG firewall.#sophosfirewall #l2tpvpn #sophosxgfirewall #sslvpn #sophosfirewall #sophosx. The Layer Two Tunneling Protocol (L2TP) enables you to provide connections to your network through private tunnels over the internet. The firewall supports L2TP as defined in RFC 3931. Note To activate a connection, you must first enable L2TP. Click Show VPN settings and click the L2TP tab. Follow the steps below to configure the iPad to connect to your Sophos XG using an L2TP VPN. Click the main menu of the iPad and go to Settings General Network. Click VPN Add VPN Configuration Select L2TP and complete the following fields. Allow leasing IP address from RADIUS server for L2TP, PPTP, and Sophos Connect client When users are authenticated using a RADIUS server, use the IP address provided by the RADIUS server. If the RADIUS server provides no addresses, XG Firewall assigns the static address configured for the user or leases an address from the specified range.

You can use policies when setting up IPsec or L2TP connections. The default set of policies supports some commonly used VPN deployment scenarios.

General settings
- Key exchange
- Internet Key Exchange (IKE) version to use. IKEv2 requires less bandwidth than IKEv1 and has EAP authentication and NAT traversal included, among other improvements.
- Authentication mode
- Mode to use for exchanging authentication (phase 1) information.
- Key negotiation tries
- Maximum number of key negotiation trials.
- Allow re-keying
- Allow the negotiation to be initiated automatically by either peer before the current key expires.
- Pass data in compressed format
- Pass data in compressed format to increase throughput.
- SHA2 with 96-bit truncation
- Available only for IKEv1. Enable truncation of SHA2 to 96 bits.
Phase 1
- Key life
- Lifetime of the key, in seconds.
- Re-key margin
- Time, in seconds, of the remaining life of the key after which the negotiation process should be re-attempted.
- Randomize re-keying margin by
- Factor by which the re-keying margin is randomized.
- DH group
- Diffie–Hellman group to use for encryption.
- Algorithm combinations
- Combination of encryption and authentication algorithms to use to ensure the integrity of the data exchange.
Phase 2
- PFS group
- Perfect Forward Secrecy group (Diffie–Hellman group) to use to force a new key exchange for each phase 2 tunnel.
- Key life
- Lifetime of the key, in seconds.
- Algorithm combinations
- Combination of encryption and authentication algorithms to use to ensure the integrity of the data exchange.
Dead peer detection
Sophos Xg L2tp
- Dead peer detection
- Check at specified interval to see whether peer is active.
- Check peer after every
- Interval, in seconds, at which peer is checked.
- Wait for response up to
- Time, in seconds, to wait for a peer response.
- When peer unreachable
- Action to take when peer is determined to be inactive.
