2 external NIC + 1 internal NIC
Recently i have upgraded my server... 2xHDD Seagate, 1 AMD SEMPRON x64 CPU, 2 GB DDR2-800 RAM, MB ASUS M2N-MX SE Plus with RAID onboard. This configuration it's more then ok for my needs.
I have installed F-BSD 7.0 amd64 whithout any problems and surprised me because recognised integrated SATA RAID controller in RAID 0 (stripping).
But the problems begin with the NIC's card. I put three NIC's into my server:
1. external 3Com 3C905B-TX with first public IP. (IP_A)
2. external 3Com 3C905B-TX with second public IP. (IP_B)
3. onboard NIC (Nvidia) with internal IP (IP_C).
I need two external NIC's because i have two separated domains and i don't like to make alias on external NIC. And for IP_B i wand to make forward to the LAN for some services.
IP_A must serve only the local servers ... like ftp, http, dns, ssh.. and so on.
a. even if both NIC's are reported to be active by ifconfig commands, only one respond to pings from an external ip; i don't have any rule in firewall which block the icmps;
b. from LAN, both NIC's repond to pings whithout any problems;
c. i tried to setup an alias (in rc.conf i put this line: ifconfig_xl0_alias0=""inet ip_B netmask mask_for_IP_B") on the NIC that respond from WAN, but whithout results; IP_B does not respond to ping meanwhile IP_A respond very good;
d. my ISP say that both IP are functionally, with MAC addresses corectly registered;
Can anyoane help me to resolve these problems, because i'm stuck... I don't have any ideea how to... and i don't find any similar topics if i search on google.
