I have a Cisco 1841 configured for VPN connections of two types:
- Site-to-site for partners' routers (IPSec) — using different
crypto isakmp keyand
match addressfor every peer (same map name, different sequence numbers). That crypto map name is added to the WAN interface.
- Client access (PPTP) — using
accept-dialin protocol pptp.
Now, a new partner wants to connect using vpnc client. The latter needs
IPSec ID (group name) and
IPSec secret in addition to username and password. I guess that IPSec secret is pre-shared key that can be specified in
crypto isakmp key on Cisco. But I could not find any VPN tutorials involving groups. Hence, my questions:
- How to add IPSec ID (group name) and IPSec secret on Cisco router for vpnc connections? Should I add a new crypto map matching all addresses as well?
- Is it possible to add this configuration without breaking the existing setup?
