hello
at office i have ZyWall 5 that has one dynamic VPN rule configured so that 3 branch offices and 2 telecommuters can connect to main office.
ZyWall 5 is behind static IP, others are not.
there is no problem, when only one branch office or telecommuter makes VPN connection.
but when two or more VPN connections is established, only one of them can ping and acces to office network. however, SA Monitor shows 2 or 3 different VPN connections to different branch offices. Also, Logs shows that second connection is ok ("Rule [everyone] Tunnel built successfully")
at logs, there is no evidence anything abnormal, but sometimes some combination gives "inconsistent SA happens!!" error when there are 2 simultaneous VPN connections
among ZyWall 5 we have zyxel homevpn II, SSH sentinel and Prestige
2602HW-61 acting as Firewall/VPN box.any ideas?
