Expert Level Connection fields
Load Balance
On the Symantec Firewall/VPN 200 or 200R you have the option of manually setting the Load
Balance to use when using the Broadband Connection Binding feature. This setting determines
what percentage of packets are sent to either WAN port. For slower connections, use a lower value
on that WAN port for best performance. You only enter the WAN port 1 percentage; WAN port 2's
percentage is calculated from that value.
SMTP Bind
If you have Internet accounts from two separate ISPs connected simultaneously, you might have to
make sure that your e-mail (SMTP protocol) only transmits on the WAN connection associated
with your e-mail server. Otherwise, the server might reject the e-mail being sent from a different
domain. You can choose WAN1 or WAN2. "None" (no binding) is the default.
Idle Renew DHCP
If you are experiencing disconnects from a DHCP type Internet account after periods of inactivity,
enter a value into this field (minutes) after which the Symantec Firewall/VPN will try to
automatically renew the connection. You must experiment to find the best value, the higher the
better. You can also Force Renew by clicking the button.
MTU LAN PC
The Symantec Firewall/VPN negotiates the MTU size from your ISP. You should leave this value
unless for some reason the ISP is providing an MTU that's not optimal. MTU problems are
evidenced by problems seeing certain websites, sending long e-mails, or extremely decreased
performance. MTU can be set for each WAN port.
Echo Request Timeout
You should leave this setting unless told to change by Symantec support.
