Failed to connect. Winsock error code: 10060, Win32 error code: 10060, inbound Edge server > Lan server mail error.

I`ve done it twice, with install and reinstall Edge server 2013. 3d time, i`ve used clean server 2012 installation (not a template) and Exchange installation.

We have:

LAN Exchange 2013 organization, 2 servers (CAS + MBX x 2) SR1 and SR2, placed in DAG,  SR1 takes 25 inbound port through CISCO ASA and its all just fine. I installed  EDGE server in DMZ, 2nd NIC placed in "LAN-Servers". ACL between LAN-DMZ"ANY-ANY".

1. Configure Internal SMTP server on Transport Configuration Set-TransportConfig  -InternalSMTPServers 10.1.20.31, 10.1.20.32
2. On the Edge, add DNS-suffix  "domain.local", edit hosts file and add LAN Exchange servers
3. ADD local DNS Host (A)  EDGE1.domain.local with LAN IP 
4. LAN NIC leave w\o geteway, add local DNS servers 
5. DMZ NIC with gateway, DNS LAN servers either (none of external DNS records)
6. From Edge made New-EdgeSubscription -FileName "C:\Edge.xml" -Force
7. From mailbox New-EdgeSubscription -FileData ([byte[]]$(Get-Content -Path “C:\Edge.xml” -Encoding Byte -ReadCount 0)) -Site “msk-site” 
8. From mailbox  Start-EdgeSynchronization -Server SR1 -TargetServer Edge1 -ForceFullSync, success.
9. Turn off manual created External Send Connector, and checked outbound mail flow, success.
10. From mailbox SR1 Set-SendConnector “EdgeSync – Inbound to Default-First*” -Port 2525 (i`ve tryed 25 either)
11. Remaped inbound 25 port from CISCO ASA to the EDGE server DMZ Nic. 
12. Checked telnet 25 with External MX record, passed test user email availability with ms connectivity analyzer .

And... there is no inbound messages anymore. Get-Queue on the Edge, shows me inbound queue to internal Exchange servers with next error:

NextHopDomain                    :
sr1.domain.local,sr2.domain.local

Status                          : Retry

MessageCount                     : 31

LastError                        : [{LRT=16.07.2014 0:31:47};{LED=441 4.4.1 Error encountered while communicating with

                                   primary target IP address: "Failed to connect. Winsock error code: 10060, Win32 erro

                                   r code: 10060." Attempted failover to alternate host, but that did not succeed. Eith

                                   er there are no alternate hosts, or delivery failed to all alternate hosts. The last

                                    endpoint attempted was 10.1.20.25:25};{FQDN=sr1.domain.local,sr2.domain.local};{IP=10.1.20.25}]

We have no IP 10.1.20.25 and we`ve never had. Local IP`s is  SR1 -10.1.20.31, SR2 - 10.1.20.32. IP 10.1.20.25 cant be resolved, and has no ping, there is no server parameters with this IP (connectors configuration). From Edge server getting true answer by cmdlet:

Get-TransportConfig | fl InternalSMTPServers

InternalSMTPServers: 10.1.20.31, 10.1.20.32 

Well, im done with it. No ideas at all.

Last things that i have:

1. Add directly IP adresses in the "EdgeSync - Inbound" connector with replacing "--" type of smarthosts
2. Turn ESMTP off on the CISCO ASA firewall.
