Hi,

I'm receiving the following errors on initial IKE negotiation after renewing
the DHCP address on the WAN interface that my IPSEC tunnel is being built
over.  Before the renewal, the devices rekeyed several times w/ no issues.

Here's what I have configured in my ipsec.conf:

        rightrsasigkey=remoteRSAkey #actual remote side RSA pub key is here
        auto=start

Any ideas?  Let me know if you need more information.

Thanks!
