We are looking to move into an MPLS which uses a proxy to gain access to the internet.
I've read stories that it will slow performance?
I read other stories it will increase the traffic/data both WAN and LAN? if so, how?
Does it add and remove things from the header? Does this depend on the product i.e. Trend, Symantec, SonicWall.
My first thought was it adds another single point of failure but the MPLS with be part of a high availability setup with SLA's, so not too worried about that.
Any other considerations why not to use a proxy? 9 out 10 stories are reporting there is no benefit and it creates more work both implementing and support.
Sorry if it's a bit vague, if you need more info please let me know.
