I would like to know, if a router doesn't support VPN (meaning it can't be used as a VPN server) can it still route an IPsec packet? And which router I should use as a server for IPSec (AH tunnel mode) site-to-site VPN ?

I was using Router-PT in my packet tracer file, but when I wanted to configure IPSec VPN I need to change it and I'm wondering if I have to change all routers that my packet passes by.

Thank you.

  • Packet Tracer is limited to getting you through the CCNA exam, and it is missing many advanced features of real devices. – Ron Maupin May 26 at 0:11
  • Thanks for your comment. Yes, I'm aware of that, but in my networking class, they asked us to work with it, so we don't really have much choice. – Yasmine May 26 at 0:14
  • Almost nobody here uses that, so we really cannot help much. Threre are hundreds of sites for network education help. – Ron Maupin May 26 at 0:16

IPsec packets are just IP packets with encrypted payloads. Routers are unaware of the payload, so it doesn't matter if it's encrypted or not.
