Jun 30, 2020 · A VPN protocol is the set of instructions (mechanism) used to negotiate a secure encrypted connection between two computers. A number of such VPN protocols are commonly supported by commercial VPN services. The most notable of these are PPTP, L2TP/IPSec, OpenVPN, SSTP, and IKEv2.

IKEv2 VPN is a standards-based IPsec VPN solution that uses outbound UDP ports 500 and 4500 and IP protocol no. 50. Firewalls do not always open these ports, so there is a possibility of IKEv2 VPN not being able to traverse proxies and firewalls. DES is not used anymore as it is an old, weak and broken encryption algorithm, and was replaced by 3DES. AES is the standard and is being used as of today and proves to be safe and a strong symmetric encryption algorithm. However you will still find 3DES is supported with VPN gateways.

What are the advantages (other than the obvious) to using DES or 3DES for encryption & MD5 or SHA or SHA1 for authentication for VPN's? I'm setting up a 4 location VPN between some clinics to share patient information in a single DB program. That's is mostly what it will be used for, except for the techs to get in fix somethings.
The security of 3DES encryption with today's technology depends on the sensitivity of the information you are trying to protect. Clearly as technology progresses, encryption algorithms need to be Windows 7 IPSec/L2TP VPN connection problem Dec 19, 2014 Sweet32: Birthday attacks on 64-bit block ciphers in TLS Web servers and VPNs should be configured to prefer 128-bit ciphers. According to our scans, about 1.1% of the top 100k web server from Alexa, and 0.5% of the top 1 million, support AES but prefer to use 3DES. Web browsers should offer 3DES as a fallback-only cipher, to avoid using it with servers that support AES but prefer 3DES. Is SHA1 in an IPSEC VPN secure? : sysadmin With all the fuss about SHA1 being deprecated when being used for SSL certificates, does this also apply to IPSEC VPN's? I have a couple site to sites using either 3DES-SHA1 or AES256-SHA1 for encryption and wondering if it's time to upgrade. 4 comments. share. save hide report. 67% Upvoted.
