Late last year I change my Firewall S2S and Remote VPN encryption from 3DES/MD5-HMAC to AES-256/SHA-HMAC and saw almost twice speed improvement. My decision to change is after doing a thorough research for which combination is more secure and will be supported in the future. Although 3DES is unbreakable (unlike DES), MD5 and HSA1 is breakable.

However, whenever we disable the IP Security Policy, Hi, The IPSec VPN client does not seem to respect the IPSec defaults in Windows Firewall. # config vpn ipsec phase1-interface edit "spoke1" set interface "wan1" set peertype any set net-device enable set proposal aes128-sha256 aes256-sha256 aes128-sha1 aes256-sha1 set add-route disable set dpd on-idle set auto-discovery-receiver enable set remote-gw 11.1.1.11 set psksecret sample set dpd-retryinterval 5 next edit "spoke1-2" set In other words, the maximum encryption you can get via our VPN servers is: AES-256-CBC, using 384 bit message hash 'SHA384' for HMAC authentication and 2048 bit RSA handshake. For L2TP/IPsec we have set up two profiles: AES128-SHA1 and AES256-SHA1. Depending on your OS version you will get automatically AES128 or the AES256 encryption.

So is a VPN that uses SHA1 at risk? For single files like their PDF example or website certificates, Google’s research definitely shows that switching to SHA-2 is an important and necessary step. It only supports IKE1 AES256 and SHA1 Encryption & Hashing Algorithm. It has SHA256 option to establish tunnel but the vendor has advised it will not be able to de-capsulate SHA-2 256 packets. This is also supported by Azure as documented at docs.microsoft.com/en-us/azure/vpn-gateway/vpn-gateway-about-vpn-devices#ipsec IF it's a site to site VPN, you have a peer set for either side of the link, and Phase 1 will not even complete. As mentioned by a few fellow techs above, if you can move to AES256 with SHA1, it is the way to go, but as it stands - you are still in a secure position with 3DES and SHA1.

The hashed message authentication code (HMAC) is an algorithm that VPNs use to verify that transmitted data hasn’t been tampered with by third parties. DEPRECATED OPTION: --cipher set to 'aes-128-cbc' but missing in --data-ciphers (AES-256-GCM:AES-128-GCM). This needs to be fixed soon.
