Hi, I will make a site to site vpn betweeen two asa firewalls. But I have a adsl modem in front of the firewall so I need to make nat for these ports which are used by vpn. so what are these ports ? which ports should I make nat for vpn ? thanks How To Guide: Set Up & Configure OpenVPN client/server VPN This won’t work without adding a complexifying layer of NAT translation, because the VPN won’t know how to route packets between multiple sites if those sites don’t use a subnet which uniquely identifies them. The best solution is to avoid using 10.0.0.0/24 or 192.168.0.0/24 as … Short guide to VPN port forwarding : What it is, How to do it
By default, the OpenVPN connection uses UDP port 1194 however if you are having problems connecting via this protocol, you can change the port and connection protocol.. For more details on the differences of the available protocols, please refer to our Knowledge Base article below:. My Private Network supports the following ports:

It is necessary because most VPNs use an NAT firewall to stop users falling victim to malicious incoming connections. This is a useful security feature, but it is unfortunately unable to distinguish between incoming connections you don’t want and those that you do.
Both SSL VPN and ASDM use the HTTPs protocol for communication which uses port 443 by default. If we need to enable ASDM management access on the same interface as SSL VPN (usually the “outside” interface), then we must change the listening port of either the SSL VPN or the ASDM.

The best solution is to avoid using 10.0.0.0/24 or 192.168.0.0/24 as private LAN network addresses. UBNT_VPN_IPSEC_FW_HOOK Allow UDP port 500 (IKE), UDP port 4500 (NAT-T) and ESP in the local direction. UBNT_VPN_IPSEC_FW_IN_HOOK Allow IPsec traffic from the remote subnet to the local subnet in the local and inbound direction. UBNT_VPN_IPSEC_SNAT_HOOK Exclude all traffic from the local subnet to the remote subnet from NAT.
