Re: Being blocked

If somebody is blocking UDP port 500 and Protocol 50 between the 2 Cisco Routers, then the IPSec tunnel would not work. Talk to your ISP ppl and have them unblock them

Re: Being blocked

response. my understanding of udp port 500 and protocol 50 are they deal with the actual tunnelling although i could be wrong, but i am actually unable to make any kind of connection outbound at all due to this block, but am obviously leaving each site. please explain as i am a little confused.

my apologies
