SMA 400 and NSA 5600 VPN
I am new to a company that uses SMA 400 as a VPN for remote login. However, we also have NSA 5600 as main firewall, which also support VPN. Since SMA 400 end of support is in 2024, I am thinking decommission it and let NSA 5600 act as VPN server.
I would like to know what features that SMA 400 has while NSA 5600 does not in regards to VPN? What should I be aware when doing the change management?
