Cisco PIX 501 error "regular translation creation failed for protocol 47"
Posted on 2006-11-15
A user here is trying to connect to an external VPN server, using the WinXP Pro VPN client. He can connect from his home but not the office network, so I suspected the settings on the Cisco PIX 501 firewall. The syslog has this error from the connection attempt:
Nov 15 2006 11:36:06: %PIX-3-305006: regular translation creation failed for protocol 47 src inside:10.2.1.105 dst outside:188.8.131.52
Any suggestions? Both our usual Cisco config people are uncontactable and it's fallen to me to resolve this urgently. I'm naive about this so I expect I have missed a lot of important info.
