Having issues with VPN

flipmadflipmad Member Posts: 184
I am working with a Cisco 871 running OSPF with VPN/GRE. I am using a wireless WAN and my sh crypto sess indicates "Down-Negotiating". I have cleared the crypto session and retried to no avail. I have another 871 that works fine with this setup and I cannot see to figure out where it is failing. I can post SH RUN results if anyone can tell me their thoughts. However, I am racking my brain. I did plug into the wireless WAN router and confirmed that it is operational.

    I had to remove the public IPs for Security reasons. I have not applied the access-lists and confirmed the preshared keys match. The WAN (FE4) is a NAT'd address so it is dynamically pulling public IP on the host end.

    sh crypto isakmp sa
    IPv4 Crypto ISAKMP SA
    dst src state conn-id slot status
    Public IP 192.168.254.3 MM_KEY_EXCH 2011 0 ACTIVE
