Dear Friends,
I am having 2 public IP pools, one is /30 and the other is /28 routed over that /30. I had assigned the /30 IP to the WAN Interface and /28 IPs are simply added to the IP Address List. Now in Firewall NAT, i created a rule where I SRC-NAT the /24 Private IP Pool with 1 single Public IP already added to the WAN Interface. I am facing a little problem that packets was dropping, Internet occasionally stops responding for a second or two and then starts for sometime. Someone suggested me to use NETMAP instead of SRCNAT, but I am not understanding the basic difference between them except this that SRCNAT is used for specific Ports and NETMAP can be used for all ports.
Can you guys suggest me the more precise way, as I am having problem in creating multiple pools. I have about 400 users now and all of them on PPPOE, to achieve the goal I created multiple PPPOE Servers on multiple PPPOE Interfaces which are connected to different remote networks. Due to lack of Public IPs I have to assign /24 private pool with 1 static public IP. Facing problem still if some user try to connect VPN then that public IP routed to that VPN server and all the clients on that IP gets routed to that VPN destination.
Kindly Help with NETMAP, sometimes my traffic gets congested so our ISP ask me to check the NAT Entries, but as we are having CCR-1036 so didnt found any issue because always found 70k entries maximum. I think its because of SRCNAT Rule.
