I'm configuring a new Cisco ASA firewall and i'm receiving the following error "Portmap translation creation failed for icmp src inside:xxx:xxx:xxx:xxx dst outside:yyy:yyy:yyy:yyy (type 8 code 0)"
The ACL's are configured to permit any to any traffic on both the inside and outside interfaces for the time being. The inside interface has a security level of 100 and a mask of 255.255.255.0, outside interface has 255.255.255.240 mask and security level of 0.
I currently cant get see through to the far side at all. I think it maybe the NAT configuration but im not sure what way to set it up.
Any body have any ideas on this.
