ipsec vpn between f5 and srx

Hi all,

 

 

strange issue here, tunnel is up , traffic is not passing, i can see on the srx side that traffic is going through the tunnel,

 

tcpdump on the f5 shows nothing,

 

i have followed this article here :

 

https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/tmos-implementations-11-2-0/11.html?sr=24146242

 

i think that addional VS is needed but the link above doesn't say much...

 

 

Please advise,
