VPN VTI based

Hi experts,

I have configured a VTI based VPN server on a Cisco router, and the remote
site is a Cisco router that is beside a 3G nat device, the VTI interface
keep flapping between up and down

*Jan 2 19:11:24.844: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Virtual-Access33, changed state to down

*Jan 2 19:11:28.316: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Virtual-Access33, changed state to up

*Jan 2 19:12:28.364: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Virtual-Access33, changed state to down

*Jan 2 19:12:32.248: %LINEPROTO-5-UPDOWN: Line protocol on Interface
Virtual-Access33, changed state to up

Even I tried to see the virtual-access interface to discover more
virtual-access interfaces with the same setting for the remote client, any
hint about that

interface Virtual-Access32

 ip unnumbered Dialer1

 tunnel source 217.66.227.245

 tunnel destination 91.135.102.167

 tunnel mode ipsec ipv4

 tunnel protection ipsec profile SDM_Profile2

 no tunnel protection ipsec initiate

interface Virtual-Access31

 ip unnumbered Dialer1

 tunnel source 217.66.227.245

 tunnel destination 188.64.204.72

 tunnel mode ipsec ipv4

 tunnel protection ipsec profile SDM_Profile2

 no tunnel protection ipsec initiate

end

interface Virtual-Access30
