Curl: (56) Recv failure: Connection reset by peer

[shumy]

Hello, I have a network configuration with pfSense + ESXi, similar to the one posted here: https://communities.vmware.com/message/2644996#2644996 and the exact same problem reported, that is, HTTPS works fine but HTTP connection always resets!
I have verified all firewall and network configurations, and all seems good.

In attachments there is a package capture for the WAN pfSense interface (removed my public IP) for the command "curl http://www.cnn.com"
You can see a TCP reset. Other servers (like google) respond in the same way.
Other machines in the same network as the pfSense WAN interface work fine.

The only justification I can use for this, is if there's something wrong with the TCP packages! Probably the PUSH package, since the SYNC has an ACK!

I think I can solve my one problem, but I need to translate also the source IP in my NAT. Is there any way to do this?

There's no info here to advise. Outbound NAT is taken care of automatically by default and there's no need to do anything usually. Produce some network diagram perhaps.

The problem is with the ESXi. I can put an ESXi management interface on the LAN and add a NAT, however I can't change the default gateway, it's a global configuration to all VMKernels. And so the packages are unable to get out!
