ACL to allow local subnet to ping Cisco 1800 series router

itgb asked
Last Modified: 2010-04-21
We recently installed two 1841 routers (1 T1 WIC, 1 Eth) and everything is working fine except we cannot telnet or even ping from the local subnet.  These are configured as a site-to-site crossover, basically, so

Site A
  Fa0/0 -
  S0/0/0 -

Site B
  Fa0/0 -
  S0/0/0 -

And from Site A I can ping the Site B FastEth port (, but not the Site A one (  Vice-versa at site B.  I'm pretty sure this is due to needing an ACL set up that will allow local access, but when I tried to modify the ACL that comes as a default in the factory configuration I never could get anything different to happen.  (I'm familiar with the PIX OS much more than IOS).  The version of IOS on these is 12.3, if that makes a difference.  Below is an abbreviated version with details modified to protect...somebody.  I'd like to be able to ping both sides of this box, at least.  Ideally, I'd like telnet access from the local subnet only.  Any help greatly appreciated!
