Couple of things

Not a good idea to post config with public IP addresses in it although i suspect you have changed them ??

Your outside interface is 45.10.15.74

Your default route is 65.100.175.78

So it looks like you have modified your addressing ?

Anyway, when you try to ssh how far do you get ?

Danny Guillory Jr — Thu, 26 Jun 2008 21:10:02 GMT

those ip's were juct changed for the post... but i get connection refused from putty

Re: shh help

Jon Marshall — Thu, 26 Jun 2008 21:15:21 GMT

Do you know if ssh works from the inside ?

Re: shh help

Danny Guillory Jr — Thu, 26 Jun 2008 21:15:47 GMT

nope but let me try

Re: shh help

a.alekseev — Thu, 26 Jun 2008 21:16:00 GMT

conf t

ca generate rsa key 2048

after that try again ssh

Re: shh help

Danny Guillory Jr — Thu, 26 Jun 2008 21:23:09 GMT

yeah i can ssh from inside

NOT outside

Re: shh help

Jon Marshall — Thu, 26 Jun 2008 21:28:01 GMT

I can test ie. see if i get a prompt if you let me know public IP

jon.marshall4@btinternet.com

but obviously you don't have to.

Jon

Re: shh help

a.alekseev — Thu, 26 Jun 2008 21:41:37 GMT

maybe your provider is blocking SSH?

Re: shh help

Danny Guillory Jr — Fri, 27 Jun 2008 12:46:27 GMT

no, because i can ssh into the 506e thats the 501's are VPN'ing into!
