Recently we upgraded the firewall and management to R80 .10 , all services and vpn came up but we faced issues in site to site vpn . Multiple custom port applications and voip phones were not working through site to site vpn .
HO is the checkpoint and the remote site is cyberroam , we were able to telnet the port but could not able to access the application with custom ports. we created the custom port and tried, also checked the match for any other option as well but didn't work.
when we reverted it back to R77.30 everything works.
Any thoughts or inputs will be much appreciated.
