I got a lab setup simulating DMVPN with IPSec over GRE. I would like to apply an access control list to the outside interface of the routers to block everything, except for TCP/UPD ports that are needed for GRE, IPSec, IKE and those related to DMVPN implementation. Does someone know what ports should I open on the ACL? Thanks!
