NAT, DSNAT & 6001, 6003- proper setup?

Have a vanilla home network (192.168.1.1 with 24 IPs allotted, don't use all), (2nics intel, several PCs and laptops connected to home network with 2 cisco spa303 voip phones. This is the motherboard supermicro A1SRM-2558F , super fast running over VMware sphere6/ESXI
https://www.supermicro.com/products/motherboard/atom/x10/a1srm-2558f.cfm

On this new install, am getting tons of 6001, 6003 packet drops. This is effecting my bitport service and even is throttling youtube and general web browsing.
Its a new install because the old install was giving same issues- it was fine but then there was a major update and everything changed.

What I have done:

-Searched all thru forum but no great reply's on how to set up NAT or Masquerading rule which seems to override everything else.

-shut off IPS, all the other filtering, created a ANY/ANY FW rule on top, zero change in speed, logs still recording 6001/6003 drops.

-added all the IPs in exceptions, no change.

-Checked the RULEZ but Masquerading rule seems to not work (phones) if I use Internal address (192.168.1.1) vs internal network (1-24).

-Tried every permutation of this, masq on masq off, nat on, masq off, nat on, address masq on, etc just to see if I can get the same speed again. even just regular dl's are slower.

When connected direct to cable its very fast.

I know its something super simple but just need some help on this.

  • Agreed with Sachin - I'm amazed that anything works with that in there.  Also, please copy/paste a one complete log line for each direction (60001 is a drop out of the INPUT chain and 6003 is a drop out of the OUTPUT chain) instead of a picture.

    Cheers - Bob
