Adventures implementing NEM between 5520 and 5505...

SCOTT FARRAND

So, help...

I'm unsure how to best solve my issue...

I have a 5520 acting as a VPN server... and 5505's acting as clients... 

The 5505's connect fine when using "client mode" but things go sideways when I try and use NEM...  Namely, they never complete a connection...

debug vpnclient shows this repeating rather fast...  (this device is connected a Fios connection behind a gateway/router... (it's my test environment and it does work when I have the device setup in "vpnclient mode client-mode"...

Some of my remote sites are configured directly with a public IP (issued via DHCP) others are behind a 3rd party firewall/device that I have no control over... but again, these sites currently work as "vpnclient mode client-mode"...

VPNC INFO: Reconnect to new peer - 168.156.248.2

VPNC CLI: access-list _vpnc_acl permit ip host 10.1.10.33 host 168.156.248.2

VPNC CLI: crypto map _vpnc_cm 10 match address _vpnc_acl

VPNC CLI: crypto map _vpnc_cm 10 set peer 168.156.248.2

VPNC CLI: no access-list _vpnc_acl permit ip host 10.1.10.33 host 168.156.248.2

VPNC INFO: Setting SUA state to 'idle'

The primary reason I'm trying to do this is so my server admin guy can see the clients who are behind the 5505's...

I don't know how much of the config file you need to be meaningful and I'm a bit leary of posting too much anyway...

Or any suggestions on an alternative configuration for the remote sites?
