We have two networks HQ and Site1 and for some reason we can’t ping the inside IP for Site1 PIX device. We have site-site-VPN set up between the two and everything works fine except we can’t ping the Site1 PIX from internal IP. However, I can ASDM/SSH in from HQ to the external IP of the Site1 PIX.
HQ is using an ASA 5550 (22.214.171.124)
PC from HQ (172.1.64.x)
Site1 is using a PIX-515E (126.96.36.199)
PC from Site1 (172.2.64.x)
Ping from HQ PC to Site1 PC (172.1.64.x to 172.2.64.x) works fine
Ping from Site1 PC to HQ PC (172.2.64.x to 172.1.64.x) works fine
Ping from HQ PC to Site1 PIX internal IP (172.1.64.x to 188.8.131.52) doesn’t work
Ping from HQ PC to Site1 PIX external IP (172.1.64.x to Site1 external IP) works fine
ASDM/SSH from any HQ PC to Site1 PIX internal IP (172.1.64.x to 184.108.40.206) doesn’t work
ASDM/SSH from any HQ PC to Site1 PIX external IP (172.1.64.x to Site1 external IP) works fine
Everything was working fine until we recently changed the outside IP address for Site1 because we switch to a different ISP. Nothing changed on the HQ ASA or Site1 PIX other than the outside IP address on Site1 PIX. I did rebuild the site-to-site VPN tunnel between Site1 and HQ.
Thanks first in advance for any ideas/suggestions.
