Here is the config. Ive omitted some of the irrelevant inspect statements and verbose ACLS.
Its similar in operation to the basic config I posted earlier with the cryto stuff added.
I fully accept I might be doing something really stupid with this config

Great!All running tickedy boo now.
Bloody ACL's ... bane of my life! BTW have you tried this at all?Some slight issues with broken ACLs blocking IKE (my f*ck up) fixed easy enough.

A handy little FREE tool for managing Cisco configs. The real bonus for me is that it allows you to edit/add/delete individual entries in ACL's on the fly without all the tedious cutting and pasting you normally have to go through, unless you use that horrible, nasty SDM abomination Cisco provide.0 -

Downloading it now for a look. Cheers.
Yeah ACLs are a pain in the ass. I was doing most of the config through the console cable as I was using it to see the debug messages which doesn't help when pasting stuff in.
Turns out copying the config to the router via tftp didn't wipe the existing ACLs. I'm not sure why this happened. It meant I had to "erase start" reload then copy over the config via tftp to be sure it was right

It's a bit difficult to explain, but what you effectively do when you do a "copy tftp: running-config" isn't to overwrite the running config, but to create a kind of "merge" of the two, in the same way as if you'd copied and pasted the complete config to the command line in a terminal session. Some commands will be the same in both configs and have no effect, some will overrule existing ones, but some are cumulative like ACL's and IP addresses on interfaces, so you need to edit the file you're copying and put "no ..." statements in wherever you need to. A bit messy, but apart from copying to the startup-config and issuing a reload, there's not much else you can do.Turns out copying the config to the router via tftp didn't wipe the existing ACLs.

Another approach to the ACL problem is to maintain them all offline in separate files. For every ACL, put an equivalent "no access-list xxx" command at the top, and then either tftp them across, or copy and paste the contents to the command line.0 -
