IPSec tunnel ping initialization

  • Hello. I have set up a tunnel between two sites. The tunnel establishes connection perfectly.
    But I obtain a strange behaviour:

    If I ping from a PC1 from site A to a PC2 in site B, the ping not respond.
    If I ping inmediatly from the PC2 from site B to the PC1 in site A, both pings start working.

    The same with all the computers.
    Some ideas? Thanks!

  • Solved. It was a firewall rules problem.
