Hi, We have a vendor that has asked that we open UDP 500 and allow IP protocol 50 to pass our firewall. Two questions here.. 1) What is running on UDP 500, and what is IP 50 doing? Something similar to GRE(47)? The vendor claims they need this to establish a connection to their VPN. Any input would be greatly appreciated.
