Can you post a config, or at least the ACLs that you have for either of those networks?

You may need to enable logging on those particular ACLs in order for me/us to figure out why these are being denied.  

See this about turning logging on.  It will give your logs more information, including which ACL is denying these packets

Are both the source and destination address downstream from your inside interface? If so, you need to have "same-security-traffic" enabled in your configuration. Reference
