UC 520 in the main site

When I configure using as per the doc

My main site UC is having static ip in WANfor ex xxx.xxx.xxx.xxxx 255.255.255.248

Lan ip is 172.32.0.0 /24

Well the other site

Have Dyanmic ip in wan site

Lan side 192.168.10.0 /24

When I ceate the isakmp policy in the main router having static IP

Crypto isakmp policy 1

Encr 3des

Hash md5

Authentication pre-share

Group2

Crypto isakmp key sbcs address ( the remote site ip is dynamic I have dyndnshostname , but it is not accepting)

What can I do here?

Please advise.

what is the CLI rejection saying exactly?

suraj12345 · ‎05-22-2009

Cisco (config)#Crypto isakmp key sbcs address aaa.dyndns.org

^

% Invalid input detected at '^' marker.

When I try a host name instead of ip address the system says invalid input .The host name which I posted is not a real hostname (just an example).If I put my real hostname also the result is the same.

Try Hostname parameter instead?

SBCS-Mobility(config)#crypto isakmp key ?
0     Specifies an UNENCRYPTED password will follow
6     Specifies an ENCRYPTED password will follow
WORD The UNENCRYPTED (cleartext) user password

SBCS-Mobility(config)#crypto isakmp key key123 ?
address   define shared key with IP address
hostname define shared key with hostname

SBCS-Mobility(config)#crypto isakmp key key123

CISCO(config)#crypto map multisite 1 ipsec-isakmp
% NOTE: This new crypto map will remain disabled until a peer
and a valid access list have been configured.
CISCO(config-crypto-map)#

Please advise me which acl i have to define her

Esentially, the same on as Steve's.
