mssql_connect() via the server's second white IP. How?

Question

PHP

Good morning,

I have a FreeBSD server with two white IPs:

%ifconfig
em0: flags=8c02<BROADCAST,OACTIVE,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO>
        ether 00:1e:67:13:ff:63
        media: Ethernet autoselect
        status: no carrier
em1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
        options=4219b<RXCSUM,TXCSUM,VLAN_MTU,VLAN_HWTAGGING,VLAN_HWCSUM,TSO4,WOL_MAGIC,VLAN_HWTSO>
        ether 00:1e:67:13:ff:62
        inet 185.12.*.* netmask 0xffffff00 broadcast 185.12.*.*
        inet 37.202.*.* netmask 0xffffffff broadcast 37.202.*.*
        media: Ethernet autoselect (100baseTX <full-duplex>)
        status: active
ipfw0: flags=8801<UP,SIMPLEX,MULTICAST> metric 0 mtu 65536

To communicate with the outside world, 185.12 .*.* is used by default
when trying to connect to MSSQL from PHP, this IP is also automatically used.

when trying to connect:

mssql_connect('212.176.*.*:3341', 'user', 'pass');

The remote MSSQL server should think our IP is 37.202.*.* and not 185.12.*.*

How can I force PHP to use the second address 37.202.*.* to communicate with MSSQL in one of the scripts?

Answer 1

It is necessary to configure routing on the computer so that the gateway of the second white IP is used to access the MSSQL server.
