So first of i would like to thank all those that contributed to this thread to help me solve the EE4G Nat issues that have plagued me for the past few months.
But most of all i would like to thank one person in particular who today spent the best part of 3 hours taking me through some possible solutions and fixes and shining that guided light.
The person in question is Baby_Frogmella who has been a breath of fresh air in helping me with his vast knowledge and finally this afternoon after quite a few different fixes we have established the Type 2 Nat that i required, i need to sort my own VPN out but Frog certainly sorted this problem out.
We actually running the Netgear Nighthawk through the EE4G router as a ,i may opt to just use a 4g netgear router instead of these 2 but its a pricey option at nearly £300 notes so i need to see some other benefits, I'm also worried that the Billion router £220 that we just sent back did not work for some reason or another .
But basically Frog solved the issue and i am extremely grateful for his time and patience and understanding of dealing with a Novice in this department.
Thanks all for the help and especially to you Frog...
