[Skunkworks] Is it reverse NAT?

Does Cisco 881 have reverse NAT, im dealing with a unique case where no one can access mail/webmail via the public IP on the local LAN while they can access the same while outside the LAN e.g. in a neighbouring office. This applies to this appliance only, while on a Cisco Linksys, access to the mail/webmail on both LAN and off LAN is possible via public IP. --------------- Don't wait for success; hunt it down like there's no tomorrow.
