We are using one M0n0wall Box(using M0n0wall 1.22) in A city, and in city B
we have one Dlink OFL 300 box create one IPSEC tunnel (as mobile ipsec) to
that M0n0wall in City A, the tunnel works well; then after that Dlink box
power off or Internet link broken, Dlink box can not create that IPSEC
tunnel to City A again automatically, only after releasing SA of that old
tunnel on M0n0wall of City A, Dlink can create one IPSEC tunnel to M0n0wall
again. This is the problem.
I am not sure if it is about Dead peer detection (DPD) of IPSEC. Could you
help to look into this problem?
If so, Could m0n0wall support DPD? Which version of m0n0wall can support?
Any hint, comment or suggestion will be highly appreciated!
