Attempting to access the Cisco SDM on an 1811 router via http and https (neither work) in an IPSec tunnel. I get through the initial password dialog box and then SDM tries to load but the "modules" cannot be populated. Eventually I get a "communication timeout" error on the SDM and it "locks up". I am attempting to access it via the loopback interface.
--- http settings ---
ip http server ip http authentication local ip http secure-server ip http timeout-policy idle 600 life 86400 requests 10000
Any thoughts on this?
