Site2Site IPSEC VPN unable to ping remote subnet
We have establish a Site2Site IPSEC VPN between Cisco 857 router and PFSense 2.0 box, unfortunately we're unable to ping from source to destination and visa versa…..I followed this tutorial "http://doc.pfsense.org/index.php/IPsec_between_pfSense_and_Cisco_IOS" and still no luck.
We have a fully working Site2Site IPSEC VPN between 2 PFSense boxes, just an issue with Cisco 857 router to PFSense.
