The easies way is probably to configure a IPsec tunnel. Check [HPE FlexNetwork MSR Router Series Comware 7 Security Configuration Guide] and search for Configuring IPsec for tunnels.

Hi  Borislav Ivanchev,

I  saw in the document hpe Msr security configuration guide but the IPsec VPN both have static ip public interface to network internet. Currently, my network topology the headquarters using the Msr2003Ac router connect to an ADSL modem connected to network internet have static ip public but the branch using hope msr2003AC router connect to a modem 4G LTE ( I configure it worked as a 4G modem) connect to network internet have dynamic ip private from the  ISP network mobile. So I can't configure the IPsec tunnel connect between two sites, pls advise and guide me make an IPsec tunnel between the headquarters and the branch ver 4G LTE ( with dynamic ip private from the  ISP network mobile).

Br,
