[Openswan Users] Sonicwall tunnel keeps disconnecting

[Mike A. Leonetti]

It seems at random times the tunnel between the machine and the
Sonicwall device keep disconnecting.  I haven't been able to isolate how
long it takes or why.  Are there any options I may be missing?

Config:
conn sonicwall
        left=x.x.x.x
        leftsourceip=10.1.1.1
        leftsubnet=10.1.1.0/24
        leftid=x.x.x.x
        right=y.y.y.y
        rightsubnet=10.10.12.0/24
        rightid=y.y.y.y
        keyingtries=0
        pfs=no
        aggrmode=yes
        auto=start
        auth=esp
        esp=3des-sha1
        ike=3des-sha1
