So VPN is not terminated on SRX is it? And is SRX just a passthrough for the encrypted traffic (ESP or UDP4500)?
No, VPN is terminated on SRX. (UDP 500) VPN is made between SRX 100 and draytek Vigor 2120. I have one ipsec gateway address on srx, and i cant make two IPSec tunnels. Traffic goes to Vigor and through ipsec tunnel to srx. On srx, traffic needs to be seperate to different gateways.
Thanks.
