![]() ![]() Naturally you can also configure Static NAT for your servers in addition to this if you need.īut as I said I am not completely sure of your setup and its requirements. ![]() The above would configure Dynamic PAT using different public IP addresses for each LAN Nat (lan-2.wan) after-auto source dynamic LAN-2-PAT-SOURCE PAT-IP-2 Nat (lan-1,wan) after-auto source dynamic LAN-1-PAT-SOURCE PAT-IP-1 2 interfaces called "lan-1" and "lan-2"Īnd the requirement is that all the hosts on each local network should be PATed to their own public IP address If you have an ASA 5505 security appliance (version 7.2 (3) or higher) configured as an Easy VPN Client in Network Extension Mode with multiple interfaces configured, the security appliance builds a tunnel for locally encrypted traffic only from the interface with the highest security level.You can naturally give different local network different public IP address towards the Internet It should list the amount provided your ASA supports them. The outside interface of ASA1 is assigned a dynamic IP address by the service provider over DHCP, while the outside interface of ASA2 is configured with a static IP address. You can confirm the support for Security Contexts with the "show version" command on the ASA. In this article, we will focus on site-to-site IPsec implementation between two Cisco ASA 5520 appliances, as shown in Figure 2. Though, while the virtual firewall might suite your needs better in your situation (if I understood your needs correctly) it would most probably mean that you would have to get additional licenses from Cisco to enable those features. Ofcourse provided that the network behind the ASA isnt tied together also. This would also essentially provide the isolation that you want between the local network. Then you could share the same "outside" interface on each virtual firewall and have different public IP address for each firewall. This would essentially mean virtualizing your ASA and configure 5 virtual firewalls in that single hardware. The only situation on an ASA where you could possibly split even those 5 IP addresses to 5 different interfaces would be to configure the ASA in Multiple Context mode. So as you can see, you can only use 5 public IP addresses 1 IP address is the broadcast IP address of the subnet/network and CANT BE USED.1 IP address needs to be used for the gateway of that network and CANT BE USED on the ASA.1 IP address is the subnet/network address and CANT BE USED.Also notice that if you have an /29 subnet then it means you will have 8 IP address of which 5 are USABLE. Each crypto map entry has a sequence number. Typically, you would have a crypto map applied to the internet facing interface. Also, the Backup ISP (ISP-2) has assigned us the public IP 200.200.200.1 with gateway 200.200.200.2. You can do multiple site-to-site VPN tunnels. If these examples don't fit your scenario post your specifics and we can customize a config for you.You cant split that single subnet to several interfaces on the ASA as you say. Cisco ASA 5500 Dual ISP Connection Written By Harris Andrea Assume that the Primary ISP (ISP-1) has assigned to us the public IP address 100.100.100.1 with gateway 100.100.100.2. Valid for all ASA OS versions class-map inspection_default You need to have an AS to accomplish this. Static (inside,outside) tcp interface 1723 10.0.0.10 1723 netmask 255.255.255.255 For the scenario I wanted, it can only be done in a multi-homed environment.

The stock ASA configuration does not include support for PPTP passthrough by default - crazy as to why.
