Show VPN Routing on CLI

[HeikoAnkenbrand]

The following command shows detailed policy based routing on the CLI. You found the policy based VPN routes  to the corresponding external gateway. The basic Check Point table is "fw tab -f -t vpn_routing -u".

Command:

echo -e "\033[0m####################\n# VPN Routing      #\n####################";fw tab -f -t vpn_routing -u 2>&1 |grep -v "+"| awk '{split($0,a,";"); print a[8]}' |sort -ng |uniq | awk '{split($0,a," "); print a[2]}' | xargs -I % sh -c  'echo -n "External Gateway: ";echo -e "\033[0;31m % \\033[37m";echo -e "  Routing: \033[32m";fw tab -f -t vpn_routing -u 2>&1 |grep % |awk '\''{split($0,b,";"); print b[6] b[7]}'\''| sed 's/From\://'| sed 's/To\:/-/'|sort -u ;echo -e "\033[0m" '

Awsome. Thank you for sharing.

Do you have a way to reset vpn tunnel via command line?

I would like to automate vpn tu procedure.

[HeikoAnkenbrand]

Hi Kim,

I think you can use the following commands to delete vpn connections.

  vpn tu del ipsec all
  vpn tu del ipsec ip-addr
  vpn tu del ipsec ip-addr username
  vpn tu del all
  vpn tu del ip-addr
  vpn tu del ip-addr username

Regards,

Heiko

Nice command.

Is it possible to add ProxyID‘s to the routes?

When I try the show vpn routing on cli on the FW, it does not work.

[Expert@fw1-sydney-a]# echo -e "\033[0m####################\n# VPN Routing #\n####################";fw tab -f -t vpn_routing -u 2>&1 |grep -v "+"| awk '{split($0,a,";"); print a[8]}' |sort -ng |uniq | awk '{split($0,a," "); print a[2]}' | xargs -I % sh -c 'echo -n "External Gateway: ";echo -e "\033[0;31m % \\033[37m";echo -e " Routing: \033[32m";fw tab -f -t vpn_routing -u 2>&1 |grep % |awk '\''{split($0,b,";"); print b[6] b[7]}'\''| sed 's/From\://'| sed 's/To\:/-/'|sort -u ;echo -e "\033[0m" '

For me doesn't give any output for some reason. R77.30 Take 338. fw tab -t vpn_routing -u -f works though.

[AlexeyB]

Because in actual script additional param seted: "grep -v '+' ". You may use simplified command like this:

fw tab -t vpn_routing -u | awk 'NR>3 {$0=substr($0,2,28); gsub(", ", ""); gsub("; ", ""); gsub("..", "0x& "); print}' | xargs printf "%d.%d.%d.%d\t-\t%d.%d.%d.%d\tPeer: %d.%d.%d.%d\r\n"‍

Checked on many takes of 77.30

[Maria_Pologova]

Brilliant, thank you Alexey. For myself just added sorting by first column.

fw tab -t vpn_routing -u | awk 'NR>3 {$0=substr($0,2,28); gsub(", ", ""); gsub("; ", ""); gsub("..", "0x& "); print}' | xargs printf "%d.%d.%d.%d\t-\t%d.%d.%d.%d\tPeer: %d.%d.%d.%d\r\n" | sort -k1n,1‍

[Pankaj_Mishra]

Is there any option to edit VPN routes in Kernel ? I have many routes from one peer (not in my control) and I need to remove one route. Please suggest.

Hi,

I adapted the full command to work on a R77.30 Gaia, with the same display as the screenshot:

echo -e "\033[0m####################\n# VPN Routing      #\n####################";fw tab -f -t vpn_routing -u 2>&1 |grep "+"| awk '{split($4,a,";"); print a[6]}' |sort -ng |uniq | awk '{split($0,a,":"); print a[2]}' | xargs -I % sh -c  'echo -n "External Gateway: ";echo -e "\033[0;31m % \\033[37m";echo -e "  Routing: \033[32m";fw tab -f -t vpn_routing -u 2>&1 |grep % |awk '\''{split($4,b,";"); print "  "b[2] b[3]}'\''| sed 's/From\://'| sed 's/,To\:/---/'|sort -u ;echo -e "\033[0m"'‍

[AlexeyB]

Now you may compare scripts execution times. My version is faster.  Because I don't use `-f` for formating output and I call `fw tab` only once. After all my colleague just added additional sorting for outpue like this: 

sort -t . -k  1,1n -k 2,2n -k 3,3n -k 4,4n

Hi @AlexeyB,

I like your solution and created a One-liner from it that also adds grouping and coloring, which is also included with our ccc script.

[AlexeyB]

Hi, @Danny  I didn't specifically group the output so that it would be convenient to filter the output line by line, using "grep" to filter by peer or the specific network you need. Everyone can adapt this command to their own needs. I'm glad that my code was useful to someone 🙂

[Solo]

it works,thanks!
