Hello all, I'm new in F5, and i confused to how to configure LC. I'm using 2 ISP link, and a single LAN. I want to load balance outbound (for now) internet traffic. I already following the configuration guide, but still i cannot access the internet. The following are what i've done (IP Public just for reference): ISP1 subnet: 202.20.10.0/255.255.255.240 ISP1 gw: 202.20.10.1 ISP2 subnet: 101.10.10.0/255.255.255.240 ISP2 gw: 101.10.10.1 LAN subnet: 192.168.1.0/255.255.255.0 1. Creating VLANs (ISP-1, ISP-2, and LAN) and set their physical port. 2. Create self IP (ISP1: 202.20.10.2, ISP2: 101.10.10.2, LAN: 192.168.1.1) 3. Create Pool (Local Traffic > Virtual Server >Pool) default_gateway (member: 202.20.10.1, 101.10.10.1) 4. Assign Pool default_gateway to Route > default gateway 5. Create Link (ISP1: Link ISP1 Router: 202.20.10.1, ISP2: Links ISP2 Router: 101.10.10.1) 6. Create Farm VS_ALL (0.0.0.0/0.0.0.0 pool: default_gateway, Profile: default, Address Translation: Checked, Port Translation: Checked, SNAT: Auto Map. My PC configuration: IP Address: 192.168.1.100/24, gw: 192.168.1.1. Still I cannot access internet from my PC. Is anyone can help me? or if it's possible to share configuration for LC. Any help would be appreciate.. Regards, Fadhil

Hi Fadhil, That all looks good except the Address and Port Translation, those should be off by default when you create a wildcard network virtual server (I'm assuming your 0.0.0.0/0.0.0.0 vip is set to port 0 as well). Denny

Hi, thanks b4... So with the default profile, outgoing connection should be ok? but still i'm unable to connect to internet, i'll try it again later. Thanks..

Not sure which profile you're referring to, there's multiple types. Which virtual server type do you have the forwarding virtual set to? It should be Performance L4, not Standard, and should be set to use All Protocols. Denny

Dear Denny, After several trial, i figure out that i have to create SNAT pool for outgoing traffic (wildcard VS), means that i cannot only select Auto Map without creating SNAT pool. Regards, Fadhil.

hi im also new with F5, i have same scenario with fadhil, but i cant add a link it says "links must have an associated data center with it"..why is that so?..its a 6400 LTM with an add-on module LC.. thanks for any help..
