				Here's the situation before I get into the actual problem encountered now.
 
 Previously DFL 700 failed and needed replaced (primary/main site which requires 8 other locations VPN'ed into it).
 
 Installed a DIR 130 temporarily to continue enabling 8 IPSec VPN tunnels (to DFL 700's).
 
 Working okay waiting for the new DFL210 to replace the failed 700.
 
 New DFL 210 installed and all but 2 of the tunnels will enable.
 
 The error message I receive is pasted below...
 
 mismatching_hwaddrs_drop
 
 
 -------
 
 The entire error message follows (for one entry but both are the same just different addy's) ...

 I've looked it up but the answer to the problem from the manual means nothing to me.  I didn't see what it meant.
 
 I'm able to connect the 2 tunnels in question to other VPN endpoints but not to the main location.
