Apologies if this has previously been covered, I am somewhat new to the scene of working with Cisco's and the support community for that matter!
I have had an interesting task of assisting with some ISP change-overs where the existing Cisco Routers IPSec connect to multiple other offices so to try and minimise downtime a Draytek Vigor 2830 was placed on the new line at the 'central' office. The objective of this was to link the remote offices to the Draytek which so we could eventually push the traffic out the new IPsec tunnels while re-configuring the original Cisco for the new line after which, connectivity would be restored.
Now thats the boring outline provided, my problem is.. I cannot seem to get the Draytek to IPSec connect with the Cisco (870) Router. I have trawled for information on this and some setups look quite plausible... but still nothing.
Has anyone here had dealings with setting up a Draytek-to-Cisco IPSec?
Could the existing IPSec setup be complicating the matter?
I am more than happy to provide the configs if this would help shed some further light..
